After a year and a half, my girlfriend and I are having a lot less sex, almost none. We used to do it once a day sometimes 3 times a night but, now its dead. I'm late 20s my girlfriend is 3 years older; not an issue just thought it might be a relevant fact to help get me an answer.

She says that after a while this happens with all her boyfriends. That it's not me, that its her.

I consider myself a giving lover. I make sure she has an orgasm 99% of the time. In a word I consider myself a "giver". I am happy when she has an orgasm more so then when I do.

Sex is not the only part of our relationship, But it's the Best part.

When I ask her about her ex's and for her to make a comparison she says she doesn't remember.

We don't live together. She does stay over on the weekends and one day or two a weekday. I never stay at her place because she lives with her family.

I have told her before that sex is important to me and that I being very attracted to her desire it a lot. She changed and doesn't know why this happens.

Please help. I don't want to break up, but I am not going to be in a sexless relationship.

She is right that sex does change as the relationship matures. The beginning is the honeymoon phase where people go at it enough to put your average bunny to shame. It does cool down. Sometimes a lot.

I have been in a number of relationships where the only way I would get sex would be to get my partner drunk. That sounds healthy doesn't it? Understandable why I am not there any more.

The fact is that she has a lower libido. Evidence is that this has happened with all her previous boyfriends. Does she know why this happens or just that it happens? Has she gone to a doctor and had him look at this? Is this something she is concerned about? What was her reaction to you saying you don't want to be in a sexless relationship?

If she isn't going to change and this is going to be a major point of unhappiness... It might be time to move on.
