I have actually had an increase since on TRT, despite more frequent sex. I think it’s an individual thing and may be determined by how you achieve ejaculation. Since on, wife and I have sex at least 3 x per week as opposed to the 3 times per month prior. I think I have only masturbated twice since going on test, and when I did it was a lower volume and a little lackluster. At my age, I want to save it for the real thing. Maybe saving it a bit would help. I know it can be tough with libido through the roof, but I think it’s worth it if you have a partner. Big volume is a turn on for most women, showing you are really into her and is something that can’t be faked.
