Hmmm... I’m wondering if you’re going thru any kind of stress in your life? You mentioned trouble sleeping, which could be stress-related, and both stress & lack of sleep could affect your sexual functioning.
I would also recommend a visit to the Dr - you can start w/ your reg GP, see what he/ she thinks, prbly would want to run some tests. Also, prostate issues can affect sexual functioning. Even if you don’t have significant symptoms, such as a weaker urine stream, incomplete bladder emptying, waking at night to pee, etc., Prostatitis can cause dull orgasms, so the Dr will prbly want to check your prostate. If your reg Dr isn’t able to help, it might be helpful to seek out a good Urologist who deals with these types of prblms...
Good luck to you & let us know what’s found & how you’re doing.
I found that products containing tea tree oil have this effect on my orgasms. Quit all products topical or internal that contain lavender or tea tree oil. Takes a couple months to return to normal. Also masturbate as little as possible and be careful of the contents of any lubricant you use.
eh sorry everyone but my last comment i meant im in a relationship with a woman and have a one year old son.
