Im a virgin, but I have a boyfriend, and were physically close in other ways. When I get excited from his touch or kiss, I notice a milky or clear discharge from my vagina. After that, I feel weak and sometimes have pain in my legs. This also happens when I masturbate, and occasionally it causes itching. Is this normal?

The milky fluid you are describing could be normal vaginal discharge, which can vary in consistency and color throughout your menstrual cycle. However, if you are experiencing weakness, pain in your legs, and itching, it may be a sign of an underlying infection. I recommend you to consult a doctor for further evaluation and possible treatment.
