Masturbation problems

Hello im 16 and i do this for 3 yrs. everything was fine and normal until Last october 2019 my body gets cold when i reached orgasm. I tried to stop it and came back again (november 2019) and still the same. after the incident my clitoris is having like a orgasm tingling sensation up until now and sometimes even if i didnt do anything i just get orgasm but no fluid came and my body and my face become cold like nervous. Anyone pls help me!!
