I'm finding that recently, I'm ejaculating semen prior to actually having an orgasm. It's like the valve that is supposed to hold the semen is just letting it pass before climax (like it's more relaxed). I'm not feeling the same build up pressure I usually feel that I'm used to and lets me hold and delay ejaculation contemperaneously with orgasm. This started last week when I had the flu and was taking a hell of a lot of nyquil/cold medicines etc. Do you think this could have been caused by the medicine and I should just give it time to 'return to normal'? Any input would help.
