Ouch - this is tough! I agree with you, there is some really silly role-play out there. First, think out what you could say to him about the unenjoyable roleplays. Imagine the words were directed at YOU instead. Would they hurt? Would you understand the problem? Could you put it a better way? Practice saying what you want to say, even if you must talk to a stuffed toy to do so. (ancient psychologist mind shrinking trick - lol) How about some casual conversation over some kahlua-laced coffee before you give eachother a warm body-oil massage? Find a way to get on the subject when he's really listening. Gently suggest different role-plays, or some other kind of fantasy sex you want to try with him. If he's responsive, great! If not, step two: ask for what you DO want, and use redirection to stop the unenjoyable behavior. If you have a good, open relationship, he will want to please you, not just himself. You might agree to 2 role-plays of his choice per week, and the rest is non-roleplay. Sometimes tantra or erotic massage is an excellent substitute for "the usual". Both techniques tend to harmonize your desires and deepen communication. Maybe these would be good things to distract him from silliness that is spoiling your own experience. If you have to focus on not laughing, how can you relax and meet your own needs? Yikes. But there is a concern about not being honest, if he thinks you are having fun when you aren't. The longer this goes on, the more he will feel misled. Something has to be said, and it sounds like you already realized that. Good luck.
