To me thats insane. If you don't count quickies, specific times girl wanted to just give me BJ or HJ, And "special" type sex, like role playing or something I have probably gone down on the girl for a few minutes, but mostly until she comes probably 90-95% of the times I have had sex. To me nothing is sexier than making a girl come with my mouth. When I have made her orgasm super quick, or multiple within a few mins or less it is 10x better than if I got a BJ. and when I know shes freshly showered and I want to go the extra mile occasionally I'll spend some time eating her ass, and it's pretty cool when a girl gets off from that.
When I see a woman that I am attracted to big time my first thought is I'd love to lick her.
Most of the time with my long term gf the issue was opposite, while the idea of going down on a woman makes me hard, she is not especially a fan of BJ's, she liked doing it some of the time like to get me hard or going, but in situations where a GF or something would give you a BJ, she tends to give a HJ. She is not good at it all, and she knows it so I have a feeling that plays into it. I know I lick good, that almost make me love it more. So maybe he was told he is not good at it or something.
I did have an ex that did have a different smell than any other I've come across, so it probably cut me doing it in 1/2 but the main reason I didn't do it is because no matter what it took at least 45min for her to get off. And before thinking its me, it for sure is not, most any other who I've been with would at least say I know what I'm doing, even when she played with herself she said a quick masturbation session for her was 30 min. A friend of mine dated her years later, said same thing, and her eventual husband that was a friend of a friend said many times getting her off is like a chore. So if you take forever to orgasm, that could play a role.
But overall if A. what you want is him to go down on you, not always to completion, but maybe as a warm up and to get you going. B. To completion a few times a week, C. You are normal meaning orgasm within a few minutes, but under 10 or 15, Then he is the problem. Honestly I had a friend complain about the same thing to me that her husband literally did it like 5 times ever, I used to say I'll hook you up nothing needed in return, and was only kidding because didn't want to cheat on my GF, then I found out afterwards my GF was telling her and others when they chatted when some of them complained that I always did it and was amazing, that friend called me on it and when she separated with her husband many times I just went down on her, and on purpose looked for nothing else, and didn't try. Turns out she told me that was one of the sexiest things she ever did, thought it was hot I went down on her and after she came 4 or 5 times, stopped and didn't ask for anything back. My point on going on and on about this is I have many male friends that are somewhat close to my thinking and a few that like it but don't love it, only 1 I know hates it, and he is that girl I just mentioned Ex husband.
