Boyfriend playing Sexlivion (mod for the game Oblivion)?

Frankly guy acting out are just acting out. If he is perverted and does weird things in person that is a carry over. If not, then all he is doing is living out a fantasy. The fact that he is having game sex doesn't really mean a heck of a lot. It is mostly him and his mind. Sort of like when you are having sex and thinking of someone else making love to you. (Assuming of course). Talk to him about it and see if you can participate. Find you some male to make sexlivion with and see if the game gets thrown away!
