1. He’s Selfish

If he's selfish in your relationship, he'll be just as selfish in the bedroom. That means sex will be all about him, and you won't get a chance to orgasm.

2. He’s a Bad Kisser

If you don't like kissing him, why would you even consider sleeping with him? Find someone you actually connect with.

3. He Won’t Get Tested

You don't want an STD. If he won't get tested to see if he has one, you shouldn't risk sleeping with him.

4. You're Worried He’ll Leave You

You shouldn't sleep with him to keep him around. The plan will almost always backfire.

5. He’s Being Pushy

A good guy will wait until you're ready. If he's pressuring you, then you should find someone who actually respects you.

6. You Have Nowhere Private to Go

You shouldn't have sex with him in the backseat of a car. If he's unable to take you to a private room with a big comfy bed, then you shouldn't have sex with him.

7. You’re Not Attracted to Him

You're not shallow for turning down a man you find unattractive. Looks matter when it comes to sex.

8. He Tells Everyone about His Sex Life

Do you really want the rest of the world knowing what happens behind closed doors?

9. He Doesn’t Respect You

Never let a man treat you like you're inferior. You two are equals, and he should act like it.

10. He Doesn't Want a Relationship

If he doesn't want to call you his girlfriend, but you want him to be your boyfriend, you shouldn't sleep with him. You'll end up with a broken heart.

11. He Won’t Use a Condom

Condoms are the only way you'll be able to protect yourself from STDs and pregnancies. If he won't use a condom, you shouldn't waste your time with him.

12. You Don’t Trust Him

If you think he's going to cheat on you, don't give him the satisfaction of having sex with you.

13. He Makes You Feel Ugly

Sex should make you feel beautiful. If you're going to be worried about your looks the whole time, then you shouldn't even go through with it.

14. You Don’t Have Any Chemistry

You won't have a good time, unless you're sleeping with someone you have a connection with. Wait for a man you can't wait to sleep with.

15. He Won’t Listen to “no”

If sex ends up hurting, he should climb off of you. But if he doesn't listen to the word "no," you're going to have a problem on your hands.

16. He Makes You Uncomfortable

You should only sleep with men you're comfortable around. Otherwise, you'll have a horrible experience.

17. You Don’t Actually Want to

If you don't want to sleep with him, don't sleep with him. It's as simple as that.

Don't make the mistake of sleeping with the wrong man. What other red flags should stop you from having sex with a certain someone?
