How often does you man masterbate?

I have been trying hard Lately to please my husband. Cause I caught him multiple times jacking off. Even if we just had sex not even 24 hours ago. 2 days in a row. Every other day. He continues to jack off. Sometimes not even bothering to ask me if I want to have sex. I feel like I am not good enough. Being married I feel we shouldn't have to. But when something comes along where I am sick or had a baby then he can take care of him self cause I can't. He can't even wait a whole day.  We had sex yesterday. Today while watching football he tried and I said not right now. We have 2 kids that were obviously awake. Well with out me knowing he went to the bathroom and jacked off. I never thought anything of it. Later I went to the bathroom and saw his wet underwear lying on the floor. I asked him about it... And yup I was right. He couldn't have waited till later or for goodness sakes tomorrow? Could he really not survive.
