I need suggestions

So I’m 17 and I have been masturbating since I was in year 6. It’s been a while and I’m getting really sick of just using my fingers and the shower head. I’m a virgin and my parents are very strict so I haven’t got a boyfriend either. I can’t buy any toys because if my parents find it I’m more dead then a door nail.

So is there anything else that I could use to penetrate myself that is hygienic and feels good at the same time?
