Is this normal?

Masturbation is touching or playing near your private part for pleasure.Some girls insert somethings inside their vagina this can be treacherous and painful though.

Can virus and prescription drugs interrupt or alter your monthly period?

masturbating is when you touch yourself for pleasure

Cherry popped?

masturbating is when guys or girls touch their genitals until they arrive at orgasm. Orgasm is a climax of sexual pleasure. Women stick their fingers into the vagina or rub the clitoris...men rub their penis until they reach orgasm...it's confusing and might even seem to be gross...sorry :( but I hope this helps for a while...email me if you want...i accept emails!

Is it everyday to have to progress a super tampon every two hours?

i am also in 7th status and not too many relatives in my category have have sex but a few have and regret it then again masturbating is like have sex with out a "partner" and using fingers or as you said intimateobjects. DON'T listen to boys in your class my BEST FRIEND is a boy and he talks in the region of sex and womanly features all the time but we give the brush-off him and also some people might get it up to try to be cool but do the right thing and stay a virgin similar to me Email me if you wanna talk and be friends!!
