I am seriously considering divorcing my husband but am I being a quitter too early?

My husband and I have been together for 5 years and married for 1 year. After our honeymoon I caught him on a transgender dating app and sexting with someone from the site, in addition to flirting other girls that he knows. Then I saw him rating cocks in another sub so I asked if he was attracted to men and he finally admitted to being bisexual. Now, we’ve had a dead bedroom for a while now and he hasn’t been able to hold an erection, so I was wondering if he was really gay and scared to tell me. In addition to that, he never does any foreplay (because he states “he’s not good at it”) and when he’s ready for sex he either wants a BJ or to have sex really hard and fast for 2 minutes or less and done. Sounds like some porn shit, right? So of course, I asked him and he said that it’s due to him masturbating way too much (over stimulation) ever since he was young and he’s researching if he did damage to his body or something. So he suggested buying me some toys to get off on. I told him that I didn’t want any toys because I thought I got married to have lots of wild and adventurous sex with my husband. Don’t get me wrong I like toys but I wanted to have a strong sexual relationship first before introducing other styles of play. It just seems like every week there’s something new and I’m at the point where I’m not even interested in having any type of sex with him at all but I’m extremely sexually frustrated. Am I giving up too early??
