There are so many different things to do together besides missionary. And while I will not go into it
Oh wow we have done many many things that would probably make you blush or go "WTH"! LOL
Some of my fear is we have went through the long long list of sexual things. And now that he has had most of his fantasies fulfilled he is slightly bored. We have done WAY more than missionary.
But I do like most of your advice
