My longterm gf loves my size, and it is a big turn-on for me when she mentions that fact. But--very important--our total relationship certainly is not centered around my size, and she certainly didn't get into the relationship because of my size in the first place since she didn't know about my size before our relationship started. Our love for each other is based on other individual personal qualities. As my gf puts it, my size is just a great bonus, and she would love me no matter what. (Though she has admitted that she would find it frustrating being in a longterm relationship with a guy who has a really, really tiny penis.) I would say that her enthusiasm for my size is a bonus for me too--I have been in a relationship where my size was actually a big problem for the girl, and that is no fun.
