what are the top 3 reasons why men cheat?

Can you guys enlighten the women why it is so difficult for you men to be faithful to one woman? You all know cheating is wrong, yet you still do it. When your woman even catches you, you deeply apologize but still do it again....and again...and again.

Can you give us just the top three reasons why you do it. Here are some options below...
1. Just because you can?
2. One woman isn't enough to satisfy your urges?
3. It boosts your ego to conquer a lot of women?
4. Because the woman in your life is not good in bed?
5. Because women accept it?
6. You can't even explain it..that's just how men are. It's in your genes, you need to reproduce?

I know some women cheat too, but we will come to that later. This is about men...Oya answer...
