ESPECIALLY having anything other than a warm soft tongue shoved anywhere near my butthole. lol

 
There was a Brazilian Girl in Atlanta several years ago who was famous for her "prostate massages" that she would often do without any notice to the unsuspecting Johns, "usually" to their great pleasure as so many guys seem to like this kind of thing. The first thing I told her when I walked through her door and we started getting busy was under no circumstances was she to give me one of her "surprises" I further told her "I have NEVER hit a woman before, but if you jam your fist (or even a finger) up my ass without notice I can't be responsible for my reaction" lol

 
Now if you are talking about me performing anal on the girl, well that is certainly ok with me. It's not really my thing. I much prefer pussy to ass, but if a girl likes it I am usually more than willing to oblige. Yes, it's a double standard, so sue me. lol

So if I answer my secret is out, I am a boring lay.

2)  I do not like things going in my ass.  My ass is a one way street......departures and no arrivals....accept for medical reasons.

3) Vodka Martini, Shaken not Stirred. Suck them ,  lick them, and I will love you forever.  Bite and pinch not a fan.  I don't do that to women (unless requested) and do not want it done to me.

5) Never had that done.  Lightly could be fun.  Lord know my ass is a big enough target.  I got paddled once when I was initiated in my collage fraternity.  Never again.  My ass burned for days.

6) See 2

9) No water sports .  It is degrading for both parties IMHO.  I will never, ever do a snowball.  I am a hypocrite.  I love it when a lady plays with my cum, and for those enough who CIM, letting my "gift"  flow out over your lips.    
About as far as I go is a kiss once swallowed.  

1, 4 and 8.  Toe-sucking does not turn me on, it makes me laugh; Hair-pulling would mean my slightly-thinning hair would disappear even faster, and; Biting falls under not allowing anything that would leave a mark on my body (this includes hickeys).  These three are a hard no, and non-negotiable no matter what she says.  Everything else is YMMV depending on the girl and how much she has turned me on in the moment.  However, like with GaG, Anal is a one-way street with me driving.

7 is just boring, since my typical date is now 3-4 hours.  
9 is going into deep dark areas that I don't ravel.

smelly farts

1. Felching

I'd have to say my no's are 1,2.6,8 plus fisting and any of the above that
the lady says no to.

1~Toes Being Sucked
No woman has ever offered to, asked to, or tried to suck my toes. If it were ever to happen, I can't imagine I'd be turned on by it, probably surprised and nonplussed.  
As far as giving is concerned, I've only done it to two women. The first was due to my attempts to find anything at all that would turn her on. She had given me a footjob (very sensuous, used both her feet to Jack me off), so I figured she might be into having her toes sucked. Result: nothing. She didn't stop me, but she didn't react favorably either.  Meh.
The second lady, a decade later, was REALLY into having her toes, feet, heels, ankles, everything sucked on.  Every single time we were together, it was on the menu.

2~ Finger In Anus  
I'll take it from a woman. I hope she likes receiving it from me.

3~ Nipples Being Pulled
"Pulled"? Seems a bit strange, but I do like having women stimulate mine in many ways, so I'll take it. I hope she likes receiving it.

4~ Hair Pulled
Mine is way too short. I haven't done it to a lot with women, but it certainly is a turn-on when women like having it done to them and encourage it.

5~ Spanking
I haven't had a lot of women do it to me, but I would surely like it if they did. Some are uninterested or unwilling.
I haven't done it to a lot with women, but it certainly is a turn-on when women like having it done to them and encourage it.

6~ Anal
To clarify, this is anal intercourse and/or pegging, as opposed to other acts involving the anus, like the fingering mentioned above.
A very few women have offered to let me do it to them or asked me to do it to them, I've always declined. It's never interested me. I guess that makes it a no-no for me performing it. No woman has ever offered or tried to do it to me. If that were to happen, it's a no-no from me.

7~ One Position The Whole Time  
Originally, I was going to answer BORING! But then I thought about a recent challenge I made with a woman that I would go down on her for a full hour or two if she could take it. She's game, so one day we'll try it.  If she stops me before I want her to, she loses and has to go down on me for an hour or two. If she doesn't stop me, she gets to name any sex challenge she wants me to perform on her or for her.

8~ Biting
I love it, both giving and receiving!

9~ Any Other No-No
Diaper play
Childplay (either real or roles)
Scat
Edging
Cockrings
Choking/strangulation/hands on throat
Breast-bondage
Nipple torture/punishment
Humiliation
Sissyfication
Cross-dressing
Male-on-male sexual contact of any kind
Ball-busting
Cock torture/punishment
Electrocution
Candle wax
Bestiality
