I say you should watch porn together. That will give him new ideas, let him know that doing the same thing all the time is not abnormal, and plus he may find it arousing. If this is not a possibilty for you, go to a website called Dodson and Ross. It is not a porn site. But it does discuss things of a very sexual nature, in a dignified way. Check it out. - Blu
I understand where your comming from. Perhaps he has never
Tried anything but the basics and so that's what he is sticking to. Try doing things to turn him on say when you are watching tv or in the kitchen. Show him that you want him right then and there. Write his sexy notes and leave them around his house. Make him take his mind off how he's having sex with you or where he's having sex with you and just do it. Hope this will help!
It's common at 19 to think a guy is your one and only, but this is not a very good match at all in the long-term. Trust me - you should be nice and appreciate him for what he has to offer, and just realize he has been a good boyfriend but not the last one. There are plenty of girls who will think the kind of sex he likes is perfect, and plenty of guys who are just waiting for somebody like you. Pace yourself because the absolute earliest you should settle down is around 26, and 29 would be better.
