Honestly for everyone this is different. I know people that get all kinds of tang and fap it a few times a day. I know people that do the same and havent touched a clit in 5 years. It's all your choice really man. Yea busting nuts does cause you to loose testosterone but I'm gonna tell you my personal opinion.
Do it in MODERATION
and you should be fine man. From personal experience, I have run into trouble when I wacked off daily. I couldn't stay hard enough to penetrate. It sucked it was an incredibly painful and frustrating experience. Not to mention, the chick will wonder WTF is up and her bitching during sex never makes it easier
But by the same token, I took the no fap challenge myself soon after this and I was about another week and a half in when I got the chance to have sex again. This time you wanna know what happened? It was too much! Just by making out with her and fingering her and kissing her neck, ect. I straight nutted IN MY PANTS without it even being touched!
This time I was too aroused! This all happened with one girl. Extremely fucked situations. Eventually I found my sweet spot and got right to work under that hood with my tool.
I found that If I go Mon-Fri without it and then have a couple sesh's during the weekend. It's no biggie. Also if I know I'll be humpin and bumpin the next day. I'll rub one off the previous night. Just to make sure I don't precum....again.
The point is masturbation can be like salt. Too much of it will seriously screw you. But without any your fucked too.
