Husband gets mad when i masterbat...

This is a super personal post, if you don't like reading about peoples sex life's I suggest you move along, I don't want any hate. I just really need some advice, mabye tell me how you feel about it from your prospective without being rude asf. Anyway.. I like to explore my sexuality, try new things sex toy wise, like dildos, vibrators, ect, stuff like that, it's not that my husband can't get the job done, I enjoy having sex with him but sometimes I just like to be alone and masterbat... It upsets him and he gets pissed telling me I should only want his dick and guilt trips me saying that I think he's not good enough when I've tried talking to him about it and I tell him all the time that he satisfys me yet he keeps pulling this shit every time and just today I was talking to him about how I'd like to try a vibrating dildo and he got so pissed... Its driving me crazy like is it so wrong of me to do something so natural?!... I really don't know what to do, part of me feels guilty because I know he's really insecure but I don't feel like I should have to apologize or feel bad for this... Seriously can someone else relate to any of this.......
