Herpes

How do you know if you have genital herpes I’m scared to ask my mom because I only 16 but I have bumps down there I never had sex but I used a brad new dildo that’s never touched anyone I’m scared update: my friend said she used it but she cleaned it off after but she’s also a virgin

Update 2: it turns out they were really infected hair follicles I told my my mom and she took me to get them checked, I also yelled at my “friend” and know we aren’t talking
