I don't think so much addiction as a fetish. Many people have fetishes to many different objects, and it sounds like he is one of them. As long as nobody is getting hurt, I am sure it's harmless.
yes, I am an addict. I subscribe to many pantyhose web sites, buy used hose from the models on those sites, and typically only get aroused when my wife is wearing them
Yes there is such a thing, I had a boyfriend once who was also addicted to pantyhose, there isn't much you can do but accept it and wear some sexy hose and play along with him.
Yes. I just divorced my husband because of it. Started out as an innocent fetish, but morphed into a full blown addiction over time. He loved it more than me so I had to go. email me at freeunow atyahoo.if you need to talk. Get out. good luck
