You should waste neither money nor time on them. They're the types who know that men are horny, gullible, and will do anything for women. So if they're putting out , why should they settle for a regular man, when they could have the cream of the crop. With today's sexual promiscuity and STD awareness, a lot more people are careful with who they take to bed. No one wants to wake up in the morning with some crazy rash.
Women are especially worried about who their potential partners have slept with.
The safest thing for partners to do is get examined by a doctor for STDs. This will reassure any worries that the two partners may have. Patience is the key to showing a woman that sex is not the only thing on your mind. If she is not ready on the first date, then wait. This might sound like a lot of time, but if you push her, she will always doubt you.
