My husband DG is ruining our marriage and sex life. He says it’s not.

I 28f have been with my husband(28) for almost 10 years total now the last few years he has had an issue with keeping an erection while he is inside of me. He says it’s because I’m not having sex with him enough. I believe it’s due to his excessive masturbation. He has admitted to me he masturbates anywhere from 3 to 5 times a day and this is all why he’s watching porn. He’ll text me during the day saying that I think his dick is small and I truthfully think he says that to me because he watches these massive black dicks on porn fucking white women. He will text me things and third person insinuating that I’m fucking someone else and coming home and letting him lick it out(cockhold? Idk I don’t watch porn. Ive watched it but it’s not real to me and does nothing for me) His dick goes soft in me and I think it’s because of his excessive porn watching and masturbation. I don’t believe masturbating that much is normal.

We’ve also been trying to have children and nothing is working in which I do have PCOS. But I believe his sperm count is just garbage because it’s not like it has any time to replenish or even become mature. I’ve asked him to please cut back on it because it’s affecting our marriage and our sex life and he downright refuses to stop says it’s not him that has the problem it’s me with the problem. I have sent him post from this account. I’ve sent him forums. I don’t know what to do anymore. It’s getting to the point where I don’t even like to look at myself naked because I feel as if I am not good enough for him we used to have the most amazing sex life When we first got together It’s now at the point where I dont even cum anymore. I’m a squirter and I haven’t in almost a year now unless I’m doing things to myself.

Any thoughts or suggestions would really be appreciated I don’t know what to do. He keeps talking about his needs his needs, but what about my needs? What do I even do with this.
