First, you got to think about whether you can support her.
Beside that does she love you so much that she wouldn't do it again
if a guy goes up to her and say i pay you $10,000 for a one night
stand? Can you truly trust her without having funny ideas? Would
you really be all right if one day, some guy come up and say "hey,
you were great last time... wanna do it again?" or when a friend is
so pissed that he sliped his tougue and say "You slut, i fucked you
tons of times before you went with my pal?"? There is a lot to
think about and worry... if you think that you are strong enough
then go for it! The choice in the end is still yours... and all the
best!
