Hello, I love the mod my only issue im having with it is for some reason I can only choose "masturbate" and not really have sex with in order to start sex animations between sims i have to start masturbating then after that i have to ask to join. It's not really fluid to do it that way so I am just wondering if there is something that i may have in the game that is kinda making that into a problem or.... am I missing something that isnt there. There are other sims on the lot, as I said they can be asked to join I just have to use Masturbate as a go between.
