USUALLY... I prefer it be one at a time.

I often find 69 distracting
& depending on the shape of my partner...
it CAN be hard to hold myself up & continue to stroke
( with mouth & or hand ).

There ARE times when I will flip around just because I feel like it...
those times are rare but, I DO do it sometimes.

WHEN I do that it is USUALLY
when a man is very close to "arrival" during a BJ &...
I feel like giving him an even HOTTER EXPLOSION.

I think the first time I did 69 ( many moons ago , MANY ) I just did not really enjoy it .
I thought it very bizarre and tried again , Yep , same result . When I then thought as to why , I came to the conclusion I just need to concentrate and enjoy .
I LOVE going down on a lady , probably more than receiving . When I am "giving" I like to be able to hear and feel what she likes and I need concentration for that .
Kinda the same when I am receiving . I like to guide your head with my hands and just enjoy it !
I'll still 69 but ...........

A guy's point of view.

While a have only partook in 69 a few times and may not be the best one to answer this, but I really really enjoy taking my time and going down on a woman until she almost squeezes my head off in ecstasy as she O's a few times....Then it's my turn.

I also find it hard to concentrate in the 69 position, not to mention getting my tongue all the places I want it to go, when I am pinned under her lovely body.  I prefer her to be on her back with a pillow under her butt, with me between her legs looking up towards her face.  This position gives me easier access to the sweet spot, and allows me to reach up and play with her boobs at the same time.

Sex with a beautifullady is good 69 time and more in anyway the two decide to do it.

Lots of times I ask a lady to switch to 69 because I'm worried her solo BJ will send me over the edge too soon and pleasuring her is distracting enough to slow me down.  I do enjoy the reactions of the lady, and often in a 69 position I've had my head squeezed between thighs & the lady raising up in her own thing (plus she gets distracted from the BJ & I can last longer).  What's always a challenge for me is that often I love the BJ so much I am tempted to just lie back & let that go to its conclusion; but at my age, being able to get back up to a useful erection so we can then do other things is far from a sure thing.  While I do really enjoy helping a lovely lady get off, I really want to have a mind-bending time as well. If we get along well, it usually works out that we both end up pretty satisfied.  I guess that's why I spend a lot of my time with repeat ladies with whom I'm pretty sure of the outcome, and that it'll be good for both of us.

I like to go down on the lady first and concentrate on making sure she is completely satisfied multiple times.  Then it is nice to sit back and receive her reciprocal efforts.  The 69 position is a great way to bring it all home, mutual arousal, adjusting the pace off each other, feeling the increasing pressure of you head being squeezed between her thighs as her pressure builds.  It can be distracting if your body sizes don't match-up well, and your neck can get tired as well.  The best 69 is when the gal crosses her legs behind my head and holds my head in position and with appropriate pressure and motion to please her; in this position I can go on pleasing her seemingly forever, but it is so erotic that I am probably lucky to last 5 minutes.

I Love better 69 with rimming and fingers Ummm

Ummmm
