Brock700 saidIt's a fact if a guy is able to get off inside a woman, then that proves he's not gay, there is no way a woman's vagina could stimulate a gay guy's penis to ejaculate. So if a guy say's he's gay and has had sex with women before then he's really bisexual. If you're able to get off in a vagina of woman ,then that proves it feels good to you which means you're bi. There is no way you can be 100% gay and feel pleasure from vaginal sex with women.
Every man, gay or straight, can have erections and thus can penetrate an ass or vagina certainly easier for a vagina than for a tight ass it will be forced to enter. Without necessarily having a sexual attraction to a partner one day.
Now if for an authentic gay, you should never have put your penis into a vagina, whatever the circumstances, it's a bit limiting.
For me, being gay is a state of mind that has nothing to do with being a virgin of all sexual relationship with women.
I began to realize I was gay when I found that I was attracted to men, first. I have taken the step when it became more intimate, with mutual masturbation and oral sex. But the ultimate step was the day when a penis penetrated my ass, with my accord. Now I was no longer a virgin. I had become a "fucked". That's my mindset. This not mean that I consider that men who have not been fucked, at least once, are not gay.
