I'm 100% with DT on giving women head...hate to be misogynistic, but seriously..take a long hard look at a vagina up close (not porn mind you) and tell me you god honestly want to lick that shit dry?!
But I definitely think getting head is better than having sex..less work involved and if she knows what she is doing, it feels better too! Also I get head much less than I have sex, so it's always a nice change
