Mastubating
I think no!
dont think so..
Probably because it's a bunch of muscles contracting.
Sure. As long as the lesbians don't mind.
Yes totally normal if you enjoy it keep doing it!
No, masturbation will not cause problems. But you have to understand that your body is not mature enough sexually.
That really is up to you. We don't all have the same stamina or the same degree of sexual excitement. Try once a day.
As long as it doesn't become overly preoccupied with it. Generally if a person can masturbate, they will.

cos*cot + sin = cos*cos/sin + sin = cos2/sin + sin = (cos2 + sin2)/sin = 1/sin = cosec
sin(3A) = sin(2A + A) = sin(2A)*cos(A) + cos(2A)*sin(A)= sin(A+A)*cos(A) + cos(A+A)*sin(A) = 2*sin(A)*cos(A)*cos(A) + {cos^2(A) - sin^2(A)}*sin(A) = 2*sin(A)*cos^2(A) + sin(a)*cos^2(A) - sin^3(A) = 3*sin(A)*cos^2(A) - sin^3(A)
