N. A fuck buddy for whom you're starting to develop feelings. It's not just about the sex anymore, but when your relationship expands to accommodate and appreciate your fuck buddy's personality, character, tastes, etc. It's when you look at his dick and see the person it is attached to.
Laura: "It took me some time to sort this out, but I...I think I've grown to like the person attached to your dick."
Jordi: *blushing* "Oh...thanks!"
