Is it normal to get a boner whenever i see young guys in their underwear
I'm bisexual but whilst seeing females in bikinis or lingerie is nice, if I see a guy in his boxers or swimming costume I get an instant boner. This is particularly the case with guys under 30 like Tom Daley, Harry Styles etc.
I'm in a straight relationship so is this why, wanting what I haven't got, and if I was in a gay relationship would it be girls having this effect on me?
