This must be the most noobie question/observation ever but here it goes:
Aren't you worried about STDs or do you plan on wearing a condom forever? Sex with a condom..yuck. Yeah, these girls are cheaper than a wife but who know where they've been and condoms are not all that effective against herpes and you can get herpes even if it doesn't show and the tests have a significant false negative rate (and some strains of herpes can be lead to serious issues down the road).
I guess if you have a live in mistress you can try and enforce monogamy but after that
