I had dick to dick sort of pushed onto me back in my DP days about twelve years ago. I had put a personal ad in Adult Friend Finder offering to help guys please their wives/sweethearts and a professional couple, very attractive wife, answered the ad and we met the following weekend.
It was my first time ever threesome and I had always envisioned myself doing a guy's wife with him watching, not necessarily participating. As it turned out it was a real turn on to see a woman in such ecstasy as we brought her to multiple and earth-shaking orgasms.
It was her idea and the first thing we did after she commanded "I want two cocks, stand up and drop your pants!". So he and I stood up, dropped the pants and underwear and there we stood, caught off guard and flaccid penises. She said she wanted them both in her mouth at the same so she got on her knees in front of us and motioned for us to bring our now almost erect cocks together, and she positioned our cocks as best she could together and tried to take us both in her mouth together. She got the heads in but her mouth didn't open wide enough.
Back then I was, in most ways, totally hetero and to have my cock shaft along side his cock shaft was not a turn on to me. (I've since re-evaluated and it would be my pleasure) To make a long story short (one that I'd be happy to share in detail another time) she had 7 great orgasms (by her husband's count) and I was invited back two more weekends.
I will say for now that I've always, since high school gym showers, been interested in seeing cocks, especially big or handsome or interesting cocks. I never allowed myself to go there even in a fantasy, but enjoyed magazines or photos of hot cocks. I am not at all interested in the man's face or even his body much, don't want to kiss a man (yuk), not into giving or receiving anal intercourse, not into men's butts, etc., but I've finally allowed myself to admit that cocks are a super-turn-on and I finally sucked a nice thick one three months back. I was jacking off while sucking his cock and came in record time. And my orgasm was fantastic! I can't wait to try it again, so I guess that makes me a cocksucker. OK with that... send pics! LOL
