But as far as MY bedroom goes, I've definitely tickled my boyfriend during sex before. My favorite is being on top but turned around facing his feet. I lean forward all the way with him still inside me and I lightly tickle his feet while we are having sex. His response is usually one of confusion. He told me once that he doesn't know whether to moan or laugh so he kind of does a mix of both which is super hot!! He doesn't have the fetish but is accommodating for me. I have a hard time tickling him if I'm on the bottom because if I grab his sides he jumps back and he can't stay inside me. Haha! I am more of a fan of upper body tickling but it's too intense for sex at times (for him not for me). So the light foot tickling or very very light side/stomach tickling (if I'm on top) does the job.
So yes it's DEFINITELY fused.
