fuck buddies?

What do you think about them? I've had one for 7 months already, no feelings or anything. However, sometimes I feel bad about it, I pretty felt like a hoe. He told me that I wasn't, that I chose him and I wasn't doing it with multiple guys. That if I wanted to I should please myself with sex. Sounds like he just told me that to keep doing it lol, but what do you think about it?
