Yeah honestly, I complain about this game a lot but I don't get what people mean when they say it's too horny. I mean, all I really know is:

1. Lae'zel is very forward, but then again she's from an entire other alien culture so who knows how gith are usually.
2. Gale seemed to have problems taking no for an answer, but from what I understand that was a bug.
3. It can feel a little weird early on when so many characters are flirting with you (because you recruit so many people and they want to give the opportunity to have their romance initiated ASAP I guess.)

But that's really it; I really don't know what people mean when they say that it's pushed on players or it's "Sleep with me or I dislike you." There's other criticisms I have (namely all the romances seem pretty shallow) but I never had this problem rejecting people.
