For me, I fantasize, I masturbate and I talk to my boyfriend about my dreams and fantasies-and we use that as a lead in to hot sex together.
I don't talk to my husband about such things, because he gets too insecure and it doesn't have the positive results.
I love people and I'm very touchy feely-but I also have been around the loop enough to know that I don't love drama and the drama with my husband is already more than I like to deal with. So I don't go chasing down activities with those I have crushes on or lust after-because I don't want the drama. It's MUCH less dramatic-and just as sexually and emotionally gratifying to tell my boyfriend all about it and have him rock my world whilst I fantasize.
