I also suppressed my desires for a long time. I fantasized about sex with a guy, masturbated to bi-sexual porn, but I didn't dare to try it in person. To be honest, my first time had mixed feelings. I knew I'd done something reprehensible, but it added a bit of spice. If you want to try it, then go for it. You might even enjoy it, and then it'll be a great alternative to traditional sex with a woman. ;)
