Man, you know how it is: you start having girls over, pretty soon they start falling in love with you...start lurking around the yard with their milkshakes. Who can live like that!? What do I tell the neighbors!?
Hahaha! I personally don't. As someone with some risk assessment in my background, I haven't done that in over 10 years..but I can imagine knowing the right lady, from previous encounters, and being able to trust my spidey-sense about her. Have some rapport first, unless you just have nothing to lose and nothing you're concerned about.
