Sex toys!!!!!

Hi all!! I was wondering if anyone had any advice for me:

I’m wanting a sex toy because I’m getting bored with my usual masturbation routine and I’m also having trouble finishing with my partner. I haven’t been able to finish with anyone besides myself. Having my boyfriend physically there or even watching me over FaceTime makes it near impossible for me to finish. I know it’s all in my head and something that I have to work on because of my anxiety. I have multiple problems though....I can’t get off with anything besides rubbing in circles at a certain tempo. I have doubts that a vibrator or dildo would help and don’t want to waste the money on something that might not work, so I was hoping someone might have advice or has experienced what I’m experiencing. Another problem I have is that my parents are VERY nosy. They keep track of my purchases on my card and my mom does random room cleanings and goes through nearly anything that I have, doesn’t matter if it’s locked or hidden away or anything, so it would be hard to hide things from her. Being open with her is also not an option because she’s very close-minded and judgmental.

Thank you in advance! Please ask any questions you want, I’m very open and open-minded.
