i am 30yrs old, i masturbate frequently, sometimes several times in a day, usually a week end on that, ive noticed that i don't ejaculate as much volume wise, and force or pressure so to speak. it use to get a bit of distance on it. now it just kinda pours out. ive also noticed less sensitivity from the tip. and it seems harder to stay erect sometimes.i also notice I'm not able to stay erect with actual sex as well, i ejaculate faster then i use to, and loose erection toi fast. when i. was younger, like maybe 10yrs ago, i could have sex a few times in a row no problem.now its like 1 and done. does any one think something is. wrong? is it just me getting older ? i still have ability to get hard. just stamina seems to be falling off a lot.
