Imagine and Choose

Imagine that you are a girl and you have a boyfriend. Your boyfriend has a very close friend and his friend is male. You're a Fujoshi, secretly you little bit happy when they're together.
Q: If you can choose, your boyfriend is the seme or uke? And gimme the reason~
I prefer my boyfriend is the seme btw, b/c I more prefer with the "cool" than the "cute". And that(imagine)'s just in your mind, didn't mean you must tell that to your boyfriend(in that situation) and ask your boyfriend to make a relationship with his friend.....just..sorry I'm bad at English TvT
