Let's define intimate as an intensely sensual feeling characterized by romantic or passionate attachment  

I don't think intimacy can be defined as one particular act, though from your list plenty of kissing comes tops.

....  care about what the other persons want and share that with each other. Whether it is shared verbally or shared physically doesn't matter. It's about sharing. So any of those acts can be in intimate, or not.  
It's different for everyone.

100% agree with this! Kissing is seriously everything!!!

Oral. Both ways.

Passionate Kissing

It's what makes men hard, and women wet = the perfect prelude to carnal sex.

... without taking our lips off each other, after a good long while led to missionary while continuing with even deeper, intense kissing.   Funny, but with all the talk of fantasies around here, I guess that rather mundane one would be mine lol

the other sexual acts can be very intimate as well but they can also just be a carnarl need to get off.
Passionate, deep  kissing is always a very intimate act. IMHO

I find it interesting that many of the ladies here will say kissing is the most intimate. Just like your post about catching an SO kissing another woman. Back in the day, if you sought out an escort, unless you got really lucky, kissing was not allowed. Why is it that here in the hobby world kissing is considered the most intimate, even taboo in the old days? For example, outside the hobby world, if you're married, and caught kissing another woman, your marriage is likely going to survive (you being the exception Robbin). However, if you're caught f*cking, chances increase exponentially your marriage won't survive. Just the opposite. It's the same thing if you go to church. Prior to marriage, if you're caught, or confess, f*cking, you're dead meat, going straight to hell. But it's okay to kiss like bunny rabbits, even on Sunday. It's always interesting trying to figure out the protocol of each particular area of life.  

I would not see a provider that does not do DFK ,  
I mean come on ladies you have some dude slip a cock inside you but  
Yet kissing is taboo???

Missionary is highly underrated by some. Man on top feels highly dominant, king of the jungle kind of thing.  

during DFK you can catch any one of 109 communicable diseases.  If you lick her pussy, the most you can get is twelve.

I’ve had my share of great luck in the hobby. A few years ago, I met a wonderful lady. She was beautiful, poetic, loved kissing, and was independently wealthy. She was in the hobby because she loved sex. What a woman! Plus, her gorgeous pussy drove me bonkers. The session started with heavy kissing. It could have ended there, and I would have been happy. When she went down on me, her skills were unbelievable. But my lips craved action, so I threw her on the bed, and started in on her. It didn’t take her long to cum hard. It was early in the session, and the sheets were soaked. An interesting thing happened. My lips lost control. After a deep breath of air, I started in on her again. Boom, this time longer and louder. When she came down, she said it was my turn. I’d never been with someone like her before, so I decided to take this as far as time, or her pussy would allow. She lasted the whole time, and even went over. I don’t know how many times she came. Probably as many times as she said, ‘it’s your turn’. I sort of went daty crazy on her. I got to see her one more time before she retired. Before she left, she gave me a cool nickname, and sent me a close up as a thank you.  

Intimacy is about connection, and that has nothing to do with menus or boxes left checked or unchecked. I've felt honest connection/intimacy in situations with a relatively limited "menu", and felt very little connection after meeting a lady who was "open minded".

Kissing is great but the most intensely intimate experience for me is DATY. My favorite is looking up at my lover as she looks down into my eyes and we have found the perfect rhythm and the perfect intensity and I have hit the perfect spot and am using one hand to press on the perfect place on her lower abdomen so each thrust she makes press against her g spot.
And we are staring into each others eyes and are perfectly matched. I have my tongue and lips and hand just right and each movement she makes I counter perfectly and we are moving as one.  
And then she has a wonderful full climax....a great gift for me...which fills my mouth and she holds my head h just where is needs to be and squeezes her legs together and fills my mouth.  
The we lie next to each other and I enjoy her after glow
 
I have had a similar sense of intimacy with facing intercourse either me on top or her on top holding my penis in her vagina and rhythmically squeezing my penis as I move in perfect sync until we both climax together.  Almost as good as the perfect DATY.

It makes me feel freaking fantastic and actually powerful to bring a woman to multiple orgasms using a combo of lips, tongue and hands.  It is the ultimate aphrodesiac that get me rock hard and ready for what (I hope) is greatly appreciative reciprocation!  I love to concentrate on the woman then let her concentrate on me because in 69 I feel I am too distracted to do my best work, (or she to do hers!)

I love a good make out session, LFK/DFK is very intimate, as your wrapped in each others arms as 2 bodies become one.. I love kissing in Mish position also for the same reasons, being balls deep inside and having her arms and legs wrapped around me as where kissing passionately. :

I would have to say BBBJs.  Some ladies have seen more dicks than a toilet bowl!

locking tongues together as our other parts are locked together too. I find it incredibly erotic to pause the dfk just long enough throughout cfs so as to hear her moans of ecstasy. I love it when we continue dfk long after we both come. It's a nice way to cool down.  

I did it! Emailed one of my local friends, and she agreed. I've witnessed all kinds of beautiful explosions in my life. They include simultaneous, wall banging, lightning, moans, groans, growls, giggles, and many more. But until today, I have never seen a woman grab a pillow, cover her mouth, and scream at the top of her lungs. It was during Big O #4. Can you believe a 40 year hobby veteran seeing something new? My huge smile won't stop. My feeling is that all of this started with your post here. I can't thank you enough. More than that, I also see just how much you help everyone here on these boards. You are truly what it's all about. You are such a remarkable woman. It is my sincere wish that we get to meet someday. If I'm ever in Vegas again, baby I owe you one.  

and I don't mean mojojo...

"I believe in long, slow, deep, soft, wet kisses that last three days!"
