Well, I’ve been lurking on this thread for almost a month, now, so I guess it’s time to 'fess up: I have never had a blowjob to climax. (There, I said it.)
My first gf and I had oral sex exactly once, about a year after we first became lovers. Even I, who’d never had a pair of lips on his tool before, could tell that she was tentative, and my thought at the time was that she’d never had a penis in her mouth. I never asked straight out if this was the case – lack of communication was the hallmark of that relationship. In that same session, I went down on her and loved it, the taste of her, the texture, the way she squirmed. She never offered again, and I never asked her to. On the other hand, I offered to eat her several times, and she always declined. I think she was afraid I would demand reciprocation but (that communication thing again) I never asked. We broke up about a year after that.
My second gf, later my wife, OTOH, had no qualms at all about taking me in. About half of our lovemaking sessions involved oral sex, but I never climaxed in her mouth. Typically she would get me good and wet (not to mention stiff), then depending on our positions, either straddle me or pull me into her to finish me off that way. It wasn’t a case of gag reflex; she would slide quite deep at times. Nor was it a case of not liking the taste; sometimes she would finish me off by hand just to watch the semen fly, then collect it to annoint her naught bits and lick it off her fingers. She just preferred to feel my climax throb in her pussy instead of her mouth. I didn’t mind
For my part, I loved to go down on her, and brought her to climax many times, both before and after despositing into her, but that was the way our relationship worked. She would cum easy and frequently had two or three climaxes (big and small) to my one.
If it had gotten to the point where I’d asked, “Honey, I’d like to cum in your mouth once, just to see what it feels like,” she would have gladly obliged, but she was taken from me suddenly before it got to that point.
