Scarleteen

Whenever I rub or touch my clitoral glands either on the sides or in the center when I masturbate my legs jerk forward or twitch.

This isn't painful or bothersome to me in any way physically but is this normal?

Yea its a natural reaction don't worry.

People react differently to stimulation, so there is no "normal" or "abnormal". As long it is not painful or hurting you I don't think you have to worry much about it.
