Once you start banging her, you try for the woman in the cubicle across from yours.
If you manage to stay employed, you are constantly broke, and you get two credit cards your wife doesn’t know about so you can keep up the appearances you need to with your girlfriends.
You just spent your mortgage payment at the strip club, or you just gave your credit card number to your dominatrix.
If you are doing things that are going to screw you over in the future, and you KNOW they are going to screw you over in the future, then your sex life has crossed the line and is now officially a problem. There are a myriad of different things that people do to get off, and whether or not you like to be tied up, or walk your girlfriend on a leash isn’t the issue.
They are just objects to use to get off, or toys to play with.
You don’t care what happens to them when you are done with them, and you will do anything to get them to do what you want.
Then, my wife tossed me out of the house because I was screwing around with so many people at places outside of work.
I wound up living with a woman that I couldn’t stand, but that would do anything I wanted sexually, no matter how deviant my demands were—I was cheating on her, too. Call it sexual compulsion if it makes you feel better.
I don’t mean this in a “Wow, look at that chick's ass! I mean, you can’t concentrate on anything for more than 10 minutes without going back into your place of fantasy.
Or if you aren’t fantasizing, you are planning your next move.
And if you aren’t planning your next move, you are having sex.
I write this list as a heterosexual man, though, this can also apply to women and LGBT individuals.
If you have none of the things on the list, good job. If you have between one and three of these, check yourself and figure out what is going on, if you have more than three, you need to find someone to talk to, and you should probably do it soon. Maybe you just cheat all the time, and lie about where you are, and how you spend your money. But, if you have sexual secrets that you refuse to share with anyone, or if somehow you figure out ways to spend Christmas with two different women (done it) then something is way, way off.
