Protip, girls: if your boy's "nice side" suddenly disappears when you're about to bang for the first time, you're entitled to kick him out until he finds it again. Pushing her down and pinning her down are awesome once she's asked for them; not before.
And no, you don't have to put out if your partner has a higher libido than you. Masturbation is a thing. Feel free to help out if you wanna, but rest assured they'll take care of it anyway even if you don't.
