Why my husband touches me only when he want sex

And ? Men often have not been used to snuggle and being touchy, esp in some cultures. And then also men normally think about sex ( not always acting on it) about anytime they touch a women.

My partner is the same, he is just not a touchy-feely romantic person, I knew that when I met him.

I wouldn't read too much into it unless this is a sudden change.

If it really bothers you then sit down and talk to him, let him know that only touching you when he wants sex really bothers you.
You will probably be very surprised by his reaction. I did this and my partner put more effort into just snuggling on the couch or holding hands.

Sometimes guys just need to be reminded that us girls appreciate the little things.

Because you let him. He probably thinks its perfectly all right. You need to TELL him. I say it so often. COMMUNICATE COMMUNICATE COMMUNICATE

More information would help in understanding what type of advice to give.

Why you got married (love, arranged, etc.), what both of your expectations for the marriage were, what type of culture he was raised in, what your relationship was like before marriage, how old each of you are, and any other pieces of background information you think would help give insight into his mindset would be welcome.
