Pls Help: My Big pen*s is Destroying My Marriage

Myself & my wife have had a problem with my penis size since we met 10 years ago. We have been married 8years now,& our sex life is dead....

We had our daughter 3 years ago which was probably the last time we Were Intimate properly so that we could have a baby.But even this was a struggle & my wife was pleased she got pregnant quickly so that we didn't have to carry on with full sex.

We went to see counselors & have seek advice from other sources, but it has all failed. All they tell you is have lots of pre-intimacy, of which we already did. We both enjoy pre-intimacy & she would be relaxed, even if she had a few drinks.

But as soon as it came to penetration i could see the pain on her face. Most of the time she would try & continue to please me, but i wanted her to enjoy it properly. We love each other like mad otherwise as we don't have any other problems.

Apart from our intimate problem, we hardly have any disputes. She has now admitted to me that she is Been Intimate with someone else only for that reason. She says that she doesn't feel any love towards him, & she still loves me &
wants to stay with me, but she just can't Be Intimate with me. I am trying my best to get my head round it, but i don't know if i can. especially when she is doing things now that i always wanted to try such as BehindBased sex. So as you can see having a large joystick isn't always such a good thing when you love someone & they have to go elsewhere to get what they want, which is sex without the pain. This is something that i can't talk to anyone about as they think you are just boasting about the size of your joystick, but this couldn't be further from the truth. Sites like this are the only times you can say what you are feeling.

pls help me, what should i do?
