I've tried being bitten by a reg. She bit my nips, lips, tongue whilst I was inside her. I lost my erection. I mananged to stop her before she tried to bite my cock to resurrect it. I hated it.
I only see regs and SA girls now, and trust and empathy has been built. A couple of them are real dirty English Girls. One started menstruating as I fisted her pussy before she asked. I loved it. She loved it and even let me film it.
But if you look at my reviews I also love gentle love making with a couple of soft fingers inside.
Depends on girl, time, mood, place (and amount of drink drunk). Lols.
