23 year old male, non porn user, I haven't had an ejaculation since November 6th but this morning (testosterone levels being higher) I slipped one out. Face down masturbation makes it easy to climax really fast. I'd been able to abstain for that long I was really hoping to make it to the two weeks. Ah well, I won't let it get me down. While I'm a slim guy at 5' 8" 130 lbs I did notice during those 12 days that I seemed to have a fuller muscular/filled out look. I'm not sure what to attribute that too. Any thoughts Marnia? I know ejaculation might use up some of the glycogen energy stores in muscle but I'm not sure how much. One thing I did notice after this morning's ejaculation is how quickly tiredness sets in. It's almost like an instant tranquilizer. I've read in numerous places that this gets worse as you age. This is one of the reasons I'd like to give up masturbation entirely. Once I climax it's instant laziness and working second shift it means my mornings are usually shot. When I finally do get out of bed I'm groggy and lethargic throughout the day. Well, I hope to check back in soon. I''m going to incorporate exercise back into my life in the next week. I went without masturbation for the first 20 years of my life. I'm really determined to see if it's possible to give it up entirely again. When I fell in love it was easy to do because I had a relational motivation. Maybe I need to start looking for a sweetheart.
