Hi,
HOpe this helps,
Set your own rules between the two of you, and set a limit... if that limit is same-room-sex but no touching, then that's as far as you go. If that limit is double anal with multiple mouth-cumshots, well then that's the limit.
What we're saying is do not change your mind to go FARTHER on-site, in the heat of the moment. That is a recipe for disaster.
