If you want to have sex with a woman who's not your wife, she can be your girlfriend, or a woman you just want to have a fling with, And you do not want to use protection, but you don't know her disease' or blood' statues! You are a very careless man. And women should avoid you. You are reckless, dangerous and a pointless man. You'll be married and still use other women for your pleasure. You will cheat on your woman and finish her with infections. Some of you girls have treated infections numerous times because of these men. A man who feels immune to the potential consequences of unsafe sex is a man who can cheat on his wife remorselessly. He doesn't care that he could get infections or that she could get pregnant (usually because he knows he can make her abort). A man such as this has no problem sleeping with any woman outside his own woman. And he will have no problem letting you know he's doing it. Men have a degree of latitude when it comes to cheating and getting away with it. But a sensible man will know not to put his girlfriend, or wife in danger because of his extrasexicular activities. That said ....if your boyfriend is cheating on you, and he doesn't care that you know, you will not be blamed for leaving him. If you find that he's cheating recklessly, and doesn't care to hide from you, or make any effort to stop. Leave him. There's another man somewhere who'll cheat and you'll never know. Or you'll know and he'll stop or will make every effort to never let you find out. Because despite cheating not being a huge deal breaker on a man, a man still has to have sense of courtesy to ensure you are respected and protected. Do not marry a mad man! May God guide every searching girl on this view to find a man who is worthy of her and protects her with everything God has given him. May you also on this view be worthy of such a man.
