Awkwardness buying toys?

I was wanting to buy a vibrator, and I never could bc I was always with family or friends or something. But now I have my own car, I was gonna go buy one. Is it awkward like paying for it in person at all? I can’t order one online bc I still live at home and my mom is really nosy. She wouldn’t open my package but she would stand over my shoulder until I did, ya know? I was gonna just go to my local Spencer’s and buy something small and cheap. Just afraid of being judged.
