Ignore the ladies. I mean, bless them, but they aren't the people you want advice from (in this context anyhow).
If you are slimy enough to pay a woman for a lap dance, a tug, or full sex, you are slimy enough to string a woman along then potentially break her heart when things get too hot for your personal comfort. So, the slimy TERB advice is to keep seeing her, use her for your entertainment, make TRIPLE, no, QUADRUPLE sure that you don't leave fingerprints of any kind (so you can deny deny deny when this blows up in your face), and enjoy the ride. To do this, though, you have to be certain that you are a creep. If you are, then enjoy!! I would.
