Ok i always want to write about gay guys having sex is that normal?
Sounds alright to me. Is this just a fantasy? Are you gay? Is there something in your past that makes you feel this way? Writing, thinking, looking, fantasizing is all normal. Doing is something totally different.
I'm a straight girl and I love hot man-on-man sex. I read Buffy the Vampire Slayer fanfiction and the best stories involve really great fucking between Spike and Angel/Angelus. If you are a fan of that show and want to write gay sex stories about the characters, I'd love to read them.
This is perfectly normal. Look up yaoi and fanfiction.net
