SC,

the alure of a BJ is - lips and tongue and teath and cheeks and throat and ...

it can drive a guy nut-nut but it is not a replacement for intercorse. Vaginal sex is great - the ole cliche - the worse one i ever had was damn good. Variation is everything - and what a way to change pace! I love waking to BJ's and it can make the love making exp[eriance last much, much longer (as long as that does not abrade the mucuse membranes).
