<s>[INST] Hello, I m a 14 year old male and have been getting wet dreams since i was 13. But i never really masturbated to ejaculation. When i masturbate and feel i almost cum i start shaking and i stop wanking and still shake for a minute or so ( my hands and legs mainly). So my question is if this is normal, thanks. [/INST] Hi, Thanks for writing. Shaking or shivering at or just before climax is experienced by few people. This can be due to exhaustion, muscle spasm and tiredness. This is due to the intense contraction of muscles in different parts of the body. This usually happens when deeper orgasms are experienced. There is nothing to worry as it happens only momentarily for a minute. It might be the result of a more focused masturbation leading to greater excitement, especially if your feet are off the ground. </s>
