I have had some darn good sex without confusing it with love myself. But there are guys who seem to fall in love pretty easily. At least they've appeared to fall in love. Who really knows. I have also had guys seem to fall in love after a single date without even a goodnight kiss. They act all jealous when I won't go out with them the next night.
I look at love as something similar to what my parents have. I've never been that close to anyone as they are to each other. They are best friends, never jealous, lovers and more. I don't expect to have something like that in a brief period of time. It takes years even to get there.
I'm also in no rush.
