What does it mean when a man is never "in the mood" for sex with his girlfriend even though he says that he loves her but watches porn whenever she out of the house?

thanks for your answer AP well firstly am 24 years old hes 29 we have been together for like 3 years, we dont have any kids and yes before ( like the 1st year of our relationship) we did have a healthy sexual relationship and now it seems that he only gives me sex when he feels like it and when i ask for sex hes always tired......but whenever i come home after spending the night out with friends and family ( which is often) i always find that hes deleted the historical part of the computer & yes he masturbates to the porn....
i have the impression that am the one that has to comply with his sexual needs whilst i just have to get it when i can and thats really frustrating

You did not give many of the details that are necessary to know exactly what the issue is here.
a. what is your age, his age?
b. is he masturbating to the porn or just looking?
c. how long have you been together
d. do you have kids?
e. did you ever have a solid, healthy sexual relationship where both of your needs were being met on a consistent basis?

Sorry to say, but from what little you have shared, it is not good. There is major dysfunction in your relationship. If you love this guy, and you have an otherwise strong relationship, then it MAY be worth the work needed to fix this.

1- Make sure he does not have a physical or emotional problem inhibiting his libido. Make him see a doctor. He may be depressed, which can kill his sex drive. He may have a ERD issue that can be diagnosed.

2- If he refuses to see a doctor, there is not much you can do, but get out of the relationship. This will not fix itself. A partner who stops having sex with their partner is a selfish partner. Not a good long term prospect.

3-Looking at porn does not always mean they are choosing porn over you. But it sounds like it may be here.

4-Sex drives usually do not match. But NEVER means none, and that is not fair to you.
