I have a weird question about something my fiancé does. He gets these really strong... urges I guess you can call them, to squeeze me. When he does it he will just squeeze my ear or arm or something like that, and make this really serious face, clenches his teeth together really hard, and squeezes. If I back away or move his arm so he can't he gets really frustrated about it until he can squeeze me. Once he gets the urge he just has to do it. He does this to our dogs too! He has Ben doing this for 2 years, uncountable times a day. We have been together for 3, it just started one day and has gotten worse ever since. Why does he do this?
