You might loose EQ and you want your eq really good and as high as possible at all times. I would get the size geneticsextender here on this site and weae that all day then work your girth at night. The extender will boost eq plus hive gains.
I like to try not to masterbate but I give in and do most men do just don't masterbate in excess and you should be fine I would masterbate 4 hours before or 4 hours after excercise. Trying to limit my ejaculation to once every one or two days.
