If you're a lady, you want to be discreet. Many men will come and go--sometimes at the same time, but sometimes you have that one dude that you can always rely on. He might live with you, although he might not be your husband. He might float you a little cash occasionally. He's got your back, and you don't want to dissappoint him. He's usually a lover.
I had a good time with Mark--he's fine as hell. I can't slip up and let John find out, though, cause he's my main man.
