One of the common casualties of long term male chastity is the ability to hold off orgasm for any length of time. Has anyone tried doing those in an attempt to mitigate or even reverse that decline? I know that some women enjoy the premature ejaculation and that there are ways to mitigate that such as strapons, penis sleeves, and numbing creams + condoms, but not every woman enjoys those and those limit the ability to be more spontaneous, so a more natural solution could be useful.
I think it's kind of like asking if there are any exercises I can do that will fix my slice if I take a couple of months off from playing golf. Can't hurt but probably won't help a lot either.
