Firstly... I just want to start by saying - I'm not gay. I have a girlfriend and I am definitely straight.

There is just this one thing that is bothering me...
I have this friend - he is my best friend in the entire world - wouldn't replace him for anything. He also happens to be my roommate.
The problem that I am having at the moment though is my weird obsession with him, in particular, his penis! :(

I have always been curious about other guys penis' - and I'm not going to lie, they do arouse me in some cases, but it never goes further than that - I have never done anything with anyone and have never really even fantasized about anything except seeing it.

I find myself obsessing about seeing my friends penis - I have seen it before, on numerous occasions, but I just want to see it more and more.
I don't know what to do? Its really bothering me - and its only his. No one else's interests me...

What coulod this be? Am I gay? I refuse to be...

Do you get straight guys who get aroused by their friends penis?

Please help me...

I have never known a straight guy that was aroused by another guys penis. You may be bi-sexual, and that's Not a bad thing.
Is your best friend gay? Then, he might not mind, but if he is straight, he might be offended.
If this is bothering you, seek out some medical help, and see how that works. Any kind of obsession isn't the best thing for you.

The first thing that comes to mind is bi-curiosity. Meaning you are curious about it; but wouldn't actually have a sexual relationship. I don't think there is anything wrong with this. Are you sexually attracted to your girlfriend? Remember that a relationship is a relationship; and cheating is cheating. We have temptations when we are in relationships. We have to do our best to suppress those feelings.

You are Bi-sexual or at least are bi-curious. Its possible you would very much dislike smoking a beef Salami if you were given a chance. That would prove a lot more. But you do like women... a lot. That means you are most definitely not gay.

Bi-curious, at least. The worriswome part of your question is the bit about refusing to be gay. I happen to be straight, but I checked out other lifestyles before settling down. Do Not Cheat!! That will hurt her, him, and you. Talk to the girlfriend, maybe she's into 3s.

The thing that bothers me the most is your obsessed with seeing his penis. Alarming!

Your trying to down play your not gay or bi but you are. For the moment your bi-curious.

I've seen most my friends naked but I don't obsessed about it nor do I get aroused. It doesn't phrase me.

But your obsession and you getting aroused at the sight of a penis tells me your not be truthful with yourself and afraid to face the truth.

You refuse to be gay?

Lets not have the argument that it is a choice,it isn't.

You can spend your whole life in denial but you are denying yourself the opportunity to find true happiness ,if in fact you are gay.
It is not the end of the world ,if you are.

Not to be too graphic but you said you're aroused by his penis- are you thinking about being with him (oral/anal) or is it just the sight? It seems that what your desires entail exactly would say a lot about your orientation.

Many people are bi-curious and choose never to act on it. Right now you are in a relationship so exploring those feelings (with any man) is not a good idea because it'd hurt your girlfriend.
