Well having been in a few serious relationships and having carried away some nice emotional scars, I've begun to notice my lack of "feeling". This girl I'm currently dating is starting to get deep emotionally and I simply feel little if anything. Naturally I'm going to slow everything down to avoid fucking her over, but I'm curious how some of you handle this type of deal (I've seen loads of people post about breaking up with the gf and such). How does it work for the rest of you porn miesters?
