i've heard that when a guy watches porn alot?

only if it is gay porn

No that doesnt mean hes gay... Lol Wow,. Maybe Hes A Virgin(:

haha no, a lot of boys watch it or have watched it, doesnt mean theyre gay

All guys watch porn. Honestly, I'd be concerned if a guy wasn't watching it at all. It's not about you, or any porn-watching guy's girlfriend for that matter, it's just something they do.

if this was true 90% of us would be gay.

No not at all. It means they are perverted, dirty, or in desperate need for some action so they watch others do it.

Not true at all. Lots of straight guys watch porn.

No thats not true, However it could mean he has a problem. Some watch for techniques and to learn though too ...

well if he's watching gay porn...! but maybe he's just trying to have a good time haha. or get ideas :p

No, absolutely not. Gays, straights males females watch porn just most are shy to admit it.
