#croos oriented

So, the other day, my friends asked whether I prefer girls or boys...(they know I’m bi.)  I got so nervous and wasn’t sure what to answer. It’s because romantically I don’t actually have a preference, but sexually, I’m not attracted to boys. But romance matters more to me, so should I say I don’t have a preference? But I feel like I would be more likely to date a girl because if I date a guy I would worry that I probably wouldn’t want to have sex with him and he would dump me...or never date me in the first place.
