I think the problem with many of these threads and similar threads is they seem to have a bit of a derogatory tone towards straight men who have had homosexual experiences. The biggest problem with this as that we are trying to label someone based merely on a few sexual experiences and not the way he chooses to sexually function.
As someone who has an incredibly large sexual appetite I began experimenting with men because the amount of sex my girlfriend and I had was not sufficient. I also believe since I was molested as a child by a man this has a lot to do with it.
I am a bit of a vouyer and also an exhibitionist and not afraid to be in the room with another naked man to start with and I have developed relationships with other men that involve kicking back and watching pornograhpy and jacking off. Yes, we looked at each others penises. In fact, I discovered it is much funner to have another hand on your penis than it is your own! Kind of like with girls! I also found it a very heightening exhilerating experience since most of the time I did this through craigslist, anonymous, in and out and you dont really even know what has been on the other side.
Through my experiences, Ive found that it is much easier to jack off with straight or bi men, there's not much pressure into finding a label or taking it to a new level. With the gay men I have met and some bi men, there seems to be this "turn you gay" thing that involves you saying you are gay or them trying to pressure you a bit into new things. However, I did meet one gay man who put it very well when he said whatever you do needs no label.
I am not ashamed of what I have done. I would not be ashamed if it came out. But I do prefer to keep it to myself. I've never kissed a man, never been a top or a bottom, and never sucked cock. I believe jacking off with another guy is definitely a homosexual experience, but I do not believe that it somehow makes me gay or bisexual.
In what I consider my life, I've dated a beautiful swimsuit model, an Indian model, many very beautiful latina, asian, and black women, and many white women. I'm white but I definitely have a sexual appeal that crosses cultural and racial boundries which is something sexually/physically I am proud of.
That's my two cents since you would like to know.
