Hisself,
Sorry you're struggling with anxiety at the moment. I think you should consider revising your goals so you ease your distress around sex. The sooner you make friendly contact with potential partners, the more relaxed you will feel.
Standard advice for anyone with sexual performance anxiety is to take all performance pressure off of yourself at first when you're with a partner. Just tell the person you want to go slowly and get to know them (for a month even). Any kind of affectionate touch and kissing is beneficial for you both, but don't try to have intercourse or even receive oral sex until you feel completely ready.
There's no rush, and the easy, relaxed contact is very good preparation for enjoyable sex. This page may have useful tips for your partner: https://eddrugs2017.com/porn-induced-erectile-dysfunction/
I think it's also good to tell a prospective partner what you've been experimenting with (rebooting). Most will be very sympathetic...and impressed.
You'll be fine. All the best.
