Is it normal i masterbate befor i go to school and before bed

Yes its normal, you are a lightweight, I remember hitting it at least five times a day. Currently, I am once or twice a day and a good day can yield 3-4. When I am dating I hold off and let it build up so my partner can appreciate it. Enjoy it! Have fun! Try some baby oil or lotion to increase intensity and sensitivity.

When I was little I used to rub on the floor before, school some times on my hands some times on my sisters hand

Masterbation is healthy it also relieves stress, anxiety, and help with depression I used to masterbait twice a day now that I am older its more like once a day. Matches make me cum hard though
