There's also gay marriage in the game, if that's the sort of thing your dad's against. There's nothing else said about that later though. You also get a 'Lover's Comfort' bonus if you sleep with your spouse, though I'm not sure if that would count, seeing as how you have to be married to get this.ĮDIT: Oh and I nearly forgot, in Dragonbridge there's a young lady whom an Imperial soldier tried to assault. The 'consummate our love' line also comes from this quest. In Sanguine's daedric quest (which you begin by accepting a drinking contest in a tavern), in your drunken haze, you're accused of 'fondling the statuary' in a Dibellan temple by a priestess. If you peek into her bedroom, there's some pretty suggestive stuff in there though.
There's one quest in which you slut-slam a promiscuous lady in Riften - Haelga, as mentioned before.
