is there any side effects of masturbating?

okay so like.. i've been always curious about this. i started masturbating when i was 13. ever since i did it, i always do it everyday, like, EVERYDAY. sometimes i even get off like five times a day cuz im always at my room. and when i have my period i cant help but to masturbate too. i even noticed that there has been a gap between my thighs when i am this chubby. and i am virgin up until now. can masturbating devirginize me? cuz i never noticed some blood when i do it and its never been painful. will it stretch my vagina? or it will still be tight? does it have any side effects on a body when i do it 2x a day? just curious pls answer me(づ￣ ³￣)づ
