foozballnow: my GF and i have been together for 3 years and have been having sex for two of those years. we have always had trouble in the bedroom and have since been trying to fix them. i have only had sex with one other person in my life and i was her first and only. i am begining to think we are not sexually compatible and though i love her deeply and would marry her, i think our differences are beginig to become a large enough factor to end things. i have tried many a time to get help and have had nothing. the first thing to keep in mind, i have a large penis. though i did read about how to deal with it on this site, nothing helps. i am about 8 x 6, give or take half an inch. the first problem we had was her getting cut. down by the base of the vagina, near the anus, she would tear upon entry or deep penetration. that has sense been mostly solved by a lot of lube and a lot of patience. now a problem we are having is frequency. i want it often and she rarely seems to want it. she doesnt even seem to get into it anymore when we are actually in the act. we are a young 20 year old couple, one would think our hormones would be through the roof. the other problem we are having is how we do it. she likes it slow and patient, while i enjoy that on occasion, i would like to do it hard and fast sometimes. we never have been able to. it hurts her too much. she feels discomfort often. we have tried lube, lots and lots and lots of foreplay, going slow to begin with then speeding up. NOTHING. ANOTHER problem is positions. we cant do it doggy because it hurts too much, there are several other positions that have the same effect. Please help me. I love her soo much and i know sex isnt everything in a realtionship, its just that i am so willing to compromise and nothing seems to be working, are we just doomed to be best friends and are simply sex incompatible, is that possible?
