Is it wrong I don't regret not pursuing the girls I fantasized about?

I'm pretty sure PMO kickstarted my desire for a relationship, and until this last school year I had no willpower/ understanding of how to go after a girl and could always justify not doing it. Yet while I wish I could have been in a relationship I don't regret not pursuing any of those girls (except the most recent one who rejected me). Most of them were just physical attractions, and I only befriended a few of them.

I just want to add one thing-
I don't just want every random woman I see, it always builds up and I'm stuck fantasizing about one until I find a replacement. Now that I've been rejected and have had no replacement, I've been contemplating where I've been.

 

I probably wouldn't have developed those fantasies had it not been for porn.

 

I'm afraid I may be developing a new physical attraction...
Just going to have to wait and see if I'll be seeing this girl again.
