Nor, that happened when my son turned 11. I couldn't hug or kiss him anymore and this bothers me so bad. I've tried to hug him once I realized this happened about 4 years to late, and it is very uncomfortable for me. He is 18 and looks like his father. I wish I could hug him and try to make an effort, but he doesn't seem to like it/or want it now.
I don't like anyone hugging or touching me except my husband and daughter.

I guess the advise I would give is don't stop hugging him ever, because he will wonder why. But may not ask why.

My son didn't ask, and he thought I didn't love him anymore.

I think the last sentense speaks for itself about hugging your son. Good luck!
