Rude boy not RUDE

I don't quite like Rihanna's songs these days. Especially the song " rude boy". what is the meaning of it anyway?
Come here, rude boy, boy; can you get it up?
Come here rude boy, boy; is you big enough?
Take it, take it baby, baby
Take it, take it; love me, love me
What?????

Tonight I'ma let you be the captain
Tonight I'ma let you do your thing, yeah
Tonight I'ma let you be a rider
Giddy-up, giddy-up, giddy-up babe
Tonight I'ma let it be fire
Tonight I'ma let you take me higher
Tonight, baby, we could get it on, yeah, we could get it on, yeah

Its like a sex song.???
