I had one of these types once. One night we had a great love-making session, and the next thing I knew, he'd backed his car over my new puppy in the driveway, sneaking out to see another woman. Sometimes womanizers grow up and grow out of it, but it can take years. Sometimes they're still hobbling after nurses in old folks' homes. Lots of guys are GIB and that means they get and give lots of sex, but not necessarily love.
Women tend to confuse having a great orgasm with being in love.
Is there something you really love about this guy, or are you romanticizing a sexual relationship. It's easy to do, but can only lead to trouble. Try to get more out of them, and they dry up like stale bread. Dear Dr. Tracy, i need help. Dear Confused, Relationships are like business deals, they either get better or they get worse.
