I think the biggest thing is to make sure you are SUPER open about sex with your S.O. and that you can talk to them openly about any outside activities. (Not with other people if you are in a closed relationship) Like my bf knows that I do the above, and we've talked about it and he is okay with it. He just asks I don't use his laptop...XD!

JL is right too. >>! My bf is the same. XD
