Am I gay if I let a guy preform oral sex on me in college?

No, you are not gay just because someone went down on you. IF you fall in love with another man, then you're gay. Otherwise, you're just a guy who experimented in college, nothing more. Look up "The Kinsey Scale" to see where you fall. Good luck.

You are either gay or bisexual

If you got sexually aroused by a man performing oral sex on you, you are probably gay. Why don't you have him perform anal sex on you just to be sure.

Why do you regret it? Is it that you now fear you may really BE gay? And if so, why? If it was just an experiment, then why feel any guilt, and what would be wrong if you actually did turn out to be gay? Too many people guilt-trip themselves about their sexuality, and their sexual experimentation. Just put it down and be who you want to be sexually, whatever way that feels right.

How about straight women having sex with women?

You seem to think there's something wrong with being gay.

This shouldn't still be such an issue with you. Did others find out, is the person still around - blackmailing you??? It should be something you tried and now know is or isn't for you. Done - gone - forget it: no one hurt, it hasn't changed you at all except expand your self-awareness.

Interesting tale.

I wonder, rather than a fellow student, what if someone offered the services of his sheep, would you have said sure, this is a place where I can try anything and do anything. How about instead they offered his grandmother or said lets give ice a go.

Sorry but your reasoning is flawed.

You did what you did because it interested you.

As for that being the dumbest of your life.

If that is it, you are miles ahead of everyone. If I could trade all the dumb decisions I have made for a head job, show me the way.

You have and will make many more dumb decisions in your life.

If you enjoyed it maybe you are not straight? I'm not one to tell you who you are and if you would rather just be straight and go on with your life go ahead.

Sexuality is not about sex. Many straight guys enjoy occasional sex with other guys and that does not make them gay any more than a gay guy having sex with a girl makes him straight. And it doesn't make you bisexual either. If you got a bad bj from a gay guy, you really struck out, most gay guys are well practiced and very good at it. If you regretted it for moralistic or religious reasons, sort them out. There is a world of sexual pleasure available if you just let it happen.
