You mean you want somebody to do you in front of him so he can learn. If so have you ask him if he is agreeable .... me think not many people will agree to something like this, a big blow to their ego.
I think the best way is to buy him the kamasutra book and also to watch porn together with him so he can learn all the tricks.
If all fail, I think you had better dump him
am sure quite a number here willing to be your partner ....
