i fooled around with a few people from highschool. 3 + 1 makes four though, i guess.

sometimes people have sexual fantasies that they like thinking about very much... but that they wouldn't really like to enact. it could be that your fantasy is a little like that...

i've heard it isn't all that uncommon for guys to have fantasies about watching girls get it on... i'd say your boyfriend would probably be stoked about your fantasy and wouldn't mind him not touching her very much so long as you were going to. but then to each their own of course and i have no idea how your boyfriend would feel about it.

i guess i think that cheating is cheating. if your partner believes that you are being faithful sexually to them and you aren't faithful sexually to them then that is cheating / misleading / lying. i guess i think that doing that would create significant trust and hence intimacy issues. on the other hand... it might be that your bf could say that he wouldn't mind you doing that. might be that he has some fantasy or other that he would like to try out so you could give each other a little bit of leeway to see. i don't have a problem with that so long as it isn't deceptive at all.
