| Well man a lot of people wouldnt consider this a problem as you get to please your woman, but I can honestly say I feel your pain.  
 A little background info I am 6'2 my gf is 5'2 and I had this problem.  She is very hyper and wants it all the time and when we first started having sex I couldnt come, and ya to do all that work without release sucks.  So the only way I was able to be able to come with intercourse mind you was to completely stop masturbating.  I had to do it for like a month straight before I got back to where I could come with her in like 45 mins to a hour.  Only other thing I can reccommend is her doing kegel exercises.
