Got an Answer?
Mine has the opposite problem of not cumming. I think it comes down to him watching alot of porn. I know he will finish from that.
Definetly buy some lingere and go to bed before him. When he gets under the sheets start to touch his penis and work your way down to suck his c*!k. When you get up force his hand to your vag so he can finger you. Once your wet get on top of him and ride like you have never ridden before!! Thats should make him come! Actually explode!!
Its either there is something medically wrong or he could be getting it somewhere else and its better so when he cant come with you he just tries wishes you would finish so he can get on with whatever else he needs to do..
Maybe play with his penis before hand and see if that make him less senstive.
Get down on him put on some sexy lingire let him watch you touch yourself.. Make it intresting.. He is probably bored..
