If you're like me, you go through spurts (pun intended) where you do it with great intensity but then cycle back to a lower level.  Hell,  even if you don't, the  only problem is if you run out of money or your dick falls off.

Sex is really wonderful stuff, and it can be powerful. But no, I've never been hooked specifically on sex with any woman.

I have, however, been hooked on the woman as a whole, with the sex being just a manifestation of my overall feelings regarding the woman.

The correct terminology for that is "fallen and can't (or don't want to) get up." It's not a problem so long as the dealings are with generally ethical people who have realistic expectations of each other.

But I am sure one to find a way to see gals that I like.

It's more than the sex though.  There's the whole aura of carefree enjoyment of the person that goes along with it.

If someday I come to the point where I'm holding up a 7/11 to get my kicks, then the term addiction might apply.

As long as you realize she is selling you companionship (someone to talk too and, perhaps, go do something with), and not someone you hope or feel is in love with you, I don't see any problem.

Probably the best thing is to keep at it until you get tired of her (I am not sure companions ever get tired of their friends, as long as their friends behave.  I could be wrong, I doubt it.)
