Just wondering what you guys favourite methods were.

A scenario, few dates with a lady, she wants to have sex with you and you want to have sex with. But through society pressures/her own moral code etc she will not have sex with someone outside of them being her boyfriend. But you do not want to be in a relationship, but still find yourself strongly attracted to this lady and want to enjoy other sexually etc.

How do you guys approach this?

Favourite methods? Best working/most simple?
