The best thing you can do for yourself in 2023 is to seek mental health counseling for your irrational HIV phobia. You don't have to live like this.
HIV is not transmitted by objects, razors, surfaces, etc. Transmission is inside the body as air inactivates the virus. the only risks are unprotected vaginal or anal penetrating sex or sharing IV drug needles to INJECT drugs. This is not only no risk but falls under the category of irrational. Do you suffer anxiety? You bought a razor, your own razor now that you've had for 4 months and think it has somehow become an instrument that spreads hiv? no. That's anxious thinking. No risk. Razors do not transmit hiv
