Is it ok to use a dildo as a virgin?

I’m a 17 yr old virgin and I’ve bought a dildo because I want to try something new but I don’t just want to have sex with some random person. Is it bad to use a dildo if I haven’t had sex yet? I don’t know why I feel guilty I just do it’s like society has made me believe hymens mean everything y’know? I’d have lost my hymen soon anyway because I’m having surgery for endometriosis and they have to go inside my vagina and told me it will stretch my hymen and technically If that’s how I define it “lose my virginity” (that’s not how I define it because it’s not sex and some people don’t even have hymens, but they had to say it in case I was from a family or culture which believed that) I just really need some input here! Help!
