In my early 20s, finishing a bad first date, he extended his hand as if to shake hands. When I took his hand, he pulled me to him and attempted to kiss me, but missed. Instead, his teeth impacted my upper lip, nearly drew blood. My follow-up punch to his ear likely nearly drew blood as well.
I've been to swingers clubs a couple of times. In my city, I found them to be a bit creepy and less than I'd hoped. I think local laws can have a big influence on their quality, and still worth investigating regardless.
One visit offered my partner and I the opportunity to play in front of an audience, which was very erotic. However, none of our fellow club goers were of the sort we wanted to join us, so we stuck to our own little show.
We've had better success at house parties arranged (and screened) by locals. Even those were a bit odd, but better than the swing clubs.
Length, girth, and shape all matter, and I suspect that every girl has a goldilocks zone where all three are just right.
It's not a matter of minimums either. Too large may have brief novelty factor, but for me, a circus cock is not something I want all the time or for long periods of time.
Technique is important, and so is chemistry, emotion, communication. I've been much more satisfied by men with smaller equipment than I usually prefer because they paid attention to my feedback and worked at pleasing me.
I think guys are too hung up on cock size. Fret over your communication skills with women instead.
There's a lot of good advice from the commentators here. I think the best and most critical is: communicate. Communicate openly, honestly, and frequently. Communication is the key to a successful relationship, whether vanilla, swinger, or whatever else.
The taste varies with partners and diet, whether they smoke, etc. However, semen is my reward for a job well done. I certainly can't let that go to waste.
Nipple and breast stimulation is fantastic as foreplay and during sex. Sensitivity and preferences are different for everyone, but your partner will almost certainly communicate what she likes and doesn't.
