I always want sex with my gf and she doesn't.

Well I am always horny there isn't one day I can't go with out a wank well atleast 7. When I get on top of any girl I will got for atleast 9 hours and then keep going I just can't stop is that normal?

When I got with my girl friend we were always having sex it was awsome btw. In the end she got pregnant and we had a boy but when she was pregnant we didn't have sex I could see why she was prego etc. Now it is 1 year 3 months since we had a good session. I get on top she cums I don't and all of a sudden I am left with palm and her 5 sisters.

She won't try new sexual things etc. Such as we were on the beach no one was around she didn't want too do it because she done it with her ex etc.

Is any of this normal?
