I love this girl to death we get along perfectly have lots of fun together. When we first met, there was huge sexual desire, she wanted it and always talked about it, then I had some anxiety and trouble staying erect and it really got to her emotionally, after that left and I dont have that problem anymore, she has the issue that my sex hurts her, she is always well lubricated but the problem is her vagina is not used to sex since it happens maybe once or twice a month, it hurts her and I have to stop, sex lasts for about 3 min, without anyone getting to orgasm. We broke up and got back together since then she has been on Lexapro medication, Every time I try and talk to her about sex she gets angry at me and says its all I talk about. I dont even want to initiate sex anymore because I always get the "im tired" or some excuse, so I tell her she needs to show me. Its been almost six months that we have been together and we have had sex a total of three times, without orgasm, each time lasting a few min, its getting very frustrating. I love her so much and want to respect her but I dont know what to do, it would be stupid of me to marry someone being frustrated but we are talking about it.
