Premature ejaculation is a huge area, with both physical and mental avenues to explore. Give this being something that has impacted you for a long time, have you considered speaking to a medical professional about it?
As a short term solution, have you considered something like a cock sleeve? It may give you a new thing to explore with a partner whilst also giving yourself some space and time to enjoy the entire act of sex?
Hubby used to suffer with this when we were first married so we decided to use condoms, which helped a lot, now being a lot older we dont need to use them and hubby lasts a lot longer now.
I’ve always suffered PE and the wank before sex used to work in my younger days and the delay spray worked and actually trained me for quite sometime as could last without it for a few years but now suffering again. I now suffer ED as well and find viagra works well for both conditions. I still come quick but can then can stay hard for round 2 and can then last without worrying about losing it
