I didn't know what's happening

Lately I have strange syndromes in my body. ....After reading or thinking about porn I start cramming and some white liquid comes out. ..I can't understand what's happening ..should I talk this with doctors or its normal thing. ..If it's normal how to handle it....I have trairoide problem and my testosterone hormone is little bit high. ... I am 20 year old nd i am virgin., I don't have bf also
