First off I'd like to give you my oppinion on your sexuality. No, I won't tell you you're gay, cause wanting a guy to fuck you doesn't mean your gay. Just the same, wanting to eat a woman out, and fuck her doesn't make me straight, either. That's why I mistakenly started out believing I was "Gay". I mean, since I find I'm attracted to men, and because I have chosen to live my life partnered with a man, I thought I was right in saying I was "gay". But the one fact still remained, even though women didn't do anything for me in porn, I could still physically get off with a woman. I also have fantasized about doing certain things with a woman. So I finally had to accept that I was actually "Bi-sexual." Unfortunately we tend to want to call poeple either straight or gay, when many are some where in between. So you may be mainly straight, but with a bi-side...on a scale of 1 (being straight) and 7 (being totally gay) you're probably a 2 or 3, where as I'm more of a 5.
Now that being said, what is there to understand about gay men? Well, we eat, sleep, work (well most of us) and some love sex, while others not so much. We are just the same as straight men. What you need to do is just be completely forward with what you want. It sounds like you want a dominate male, such as myself, who'd love to take you down, pull your pants off, and fuck you like a man would fuck a woman. If that's what you want, go on craigslist and simply state that. Tell them you're straight, but you want a man to dominate you. You'll find there'll be a lot of tops who'd be willing to step up to the plate for that job.
If you have any further questions, let me know in a personal message, and I'll try to help.
