Help!!

I have been with my fiance for a while now and we have had some problems in our realtionship but we are now both working towards making things better...my problem is that before me he simply had not been with people who were very sexually experienced or very open to doing new things and since we have been together I've done everything I know he told me that sex just really isnt very important to him but I find that hard to believe for a guy and I love to have sex I just want to find something new and exciting because I dont know what to do to get him to be more into it

Get a shoe box or another small box. Have him write his fantasies and you do the same on small pieces of paper and put them in the box. At the beginning of each month draw a paper at random from the box. Have a date set aside each month to play out the fantasy. It is SO much fun!

If you do any bondage or any other strange fantasies that might offend one partner make sure you have a safe word. Something unusual. Popcorn, banana etc. In case one partner is feeling uncomfortable they can say that word and activity can stop.

I did this with my boyfriend... at first he didn't want to do it because he was embaressed of his sexual fantasies. But once I let him in on a few of mine he gave in

ok my problem is seriously I've done everything with him I've wanted to do I honestly cant think of anything else...id like to but its hard because of the way he is im not sure where his boundries are because he is so like reserved I really dont have anything I can think of that I acutally havent done that I wanted to so im like how can I get him to open up to me like I have to him
