no thats the point, if a woman has an agreement with her BF to not get into compromising situations, if they have mutual respect, she wont let u in that position.

its a psychology thing, people tend to uphold rules of honour! this can of course be killed of by an emotional rush, but if you set it so your girl has her guard WAY before u get this chance.... her chances of bein swoon is minimal.

if however ur comfortable with ur girl goin back to a party.... with a load of lads.... there is A MUCH HIGHER chance of somethin happein here
