problem with errections

    hello,i need help pls.
    I am 37 age man,
I was in 7 years long relation,engaged,but we broke off 7 years ago.
I didn't have any problems with sex,actually we enjoyed a lot and we had normal similar sex fantasies.
After a year,our sexual fantasies had growed,we started to watch porno movies and we had started to imagine sex with another partner,that was very sexual exciting for both of us.When she started to use sex with another in reality,we broke off.
   After 7 years now i have new girlfriend that i love so much,we r together almost 8 month,we tried many times sex but without success.
  When i first time tried sex with her,she didn't like cus she said it was too early.Since now,we tried many times,sometimes i don't have errection,sometimes i have but it's not enought to penetrate,and sometimes maybe 3-4 times i succeded to penetrate but i can't keep errection.
  I like foreplay but she doesn't like long foreplay,and if she see my penis is not errected,she becames very angry.
  Now every time i try sex with her i become afraid what if i don't have an errection again.

  I have normal morning errections and masturbations almost every day,but i still have the old sexual imaginations,imagining my new girlfriend to have sex with another man.
  How to solve the problem,i think the problem is in my head.
   Pls help me
Thx

You are right. It sounds like this is all in your head you are still hung up on your ex girlfriend's betrayal. Since you say you have normal morning erections and masturbate regularly, it is safe to say you don't have a physical problem. Also, the way you described your past sex life, it sounds like you have no sexual hang ups either.

Your new partner sounds a bit like she isn't very understanding of your problem. Maybe she gets angry out of hurt because she thinks she is not attractive enough for you or that you don't find her sexually appealing. You two have to sit down and discuss this problem. You need to tell her about your past relationship and what happened and you need to tell her why you are being unresponsive to her. Make sure she knows the fault isn't with her. Also, in any healthy relationship, sexual or otherwise, there should be compromise. You like foreplay, she is not that into it. You should find a happy medium and go from there. Share your fantasies, maybe she'll open up to you more.

Good luck.
