well the only thing you can do is sit him down and have an honest conversation with him. if you are planning on having a sexual relationship with him, you should be able to do this. make him feel comfortable, and if he does ease up and actual try some stuff be totally supportive. let him know he is doing a good job and stuff! it will be a huge ego boost........ i'm not saying take it overboard and go on faking crazy porno multi orgasms. but you get my drift!
