I can't help you because I'm not attracted in any way to males... But I can tell you that I'm attracted romantically and sexually to girls, so it's definitively possible!
People aren't necessarily romantically attracted exclusively to people of the same gender, it just so happens that all the people the are/have been attracted to are of the same gender.
We're talking about horse's penises now? Last time we went there... well... you know. Don't blame me for it this time though!
We have a thread devoted to sex reaching it's 34th page on a forum that ranks first page on Google for a "zoophilia" search. How did you think it would go?
