I noticed this a little bit on our honey moon, we were having sex missionary and she takes both my hands and puts them around her neck, I look at her like what does this mean and she just said “squeeze”…so I did just a lil and that was that..as the weeks have gone on she has gotten more hardcore with it, last night she had me squeeze until she almost passed out and has now requested that I start slapping her while I squeeze, slap, squeeze then slap..it seems to work because she gets off but I don’t know how much further she going with this. Im thinking we might need to have a talk before this goes any further..if your wife did this how would you handle it?
