I catch asshole's drift, I mean if a girl doesn't want it at all (I'm not saying all rape is consensual, just that the women give up too easy) she's going to be struggling the whole damn time, and if you have someone struggling to get away from your dick you might get penetration, but not the traditional "he fucked the shit out of her until he came" BS typically portrayed. This does not hold true for gang rape, drugged women, knocked out women, or constrained women, just the "I saw her in the alley and wanted to tap that so I made her fuck me" stuff.
