I'm with him 4months... the last time we had sex was 2 moths ago... I askd him wher is the problem... he said the problem is not in me he just want to have break... is that normal?

We need more information. All I can say is that's it's unusual for a guy who is only two months into a relationship to stop wanting sex. I suspect the problem really is with him.

If he wants a break, I would agree, and go out with other guys.

There is nothing as bad for your morale as going out with a guy who doesn't want to get you naked.

How old are both of you?

I'm 18 he's 20

Do you mean a break from sex or the relationship? If it is from the relationship, all you can do is accept it and decide if you want to wait for him to figure out what he wants or if you would do better ending the relationship and moving on.

If it is from sex:

'Normal' depends on the person. What might be 'normal' for one person may not be for another.

There are many reasons for people to not want sex. Usually it comes down to stress, exhaustion, timing, or medical/physical issues. Is he worried or stressed out about work, school or family? Does he have any medical issues or is he on any medications? Does he drink a lot or use marijuana? Sometimes, the hassle of finding a place to have sex (not just a quick encounter) can wear down the libido. Do either of you have your own place or is there always a possibility of someone walking in or over-hearing?

There could be past issues causing him to back off. An ex-girlfriend getting in touch. An ex-girlfriend showing up pregnant or with a child. An ex-bedmate getting in touch about possible sexually transmitted diseases. All of these are just possibilities. Only he can tell you what his reasons are IF he is willing to open up about them.

How is the rest of your relationship? Does he show affection in other ways?

If he has told you he wants a break, you can ask for clarification and see if there is a possible compromise. However, it is up to you to decide if you want to work with him (if he is willing to work with you) or if it is too much work to keep a very new relationship going.

Good luck determining whether the relationship has promise to grow and move forward or if it has already hit its peak and is now all but officially over.
