Husband bisexual I need advice

I’ve been with my husband for 14 years. 2 years ago he admitted to being bisexual. I was accepting. Still am. But I found out in July he had a Twitter account for a year+ he was posting naked erect pictures of himself on, daily. We had sex twice in 7 months during that time. But he jacked off daily when doing this. Then I found out he had a Grindr acct and met up with someone to give and receive oral. He says only one person but idk. I asked if he prefers men to women and he said men. But he wants to be with me. We have a daughter and he’s afraid his family will disown him so I feel I’m just a cover up and will never fully satisfy him. Can someone provide some advice on this? I get the whole he cheated you should leave. I don’t want that advice. I want to know if I can ever really truly satisfy him or if he will always prefer men over me. And how can I make myself believe him when he says he’d rather be with me.
