Hello, Welcome to health care magic. I am Dr Alok Sinha, MD Psychiatry from India. I can understand your concern. I have carefully read your question and understood. I will try my best to answer your query. The situation you are facing is a very common and natural phenomenon. Whenever we see a female partner or think about her our mind becomes sexually active and as a result it send signal to genital organ through nerves. As a result erectile tissue & glands in genital organ gets stimulated. Erectile tissue makes the organ erect and glands secrete lubricating substance to facilitate the sexual act. So lubrication at the time of sexual arousal is a common phenomenon. Many person have a myth that this secretion is semen, hence call it premature ejaculation, and as a result they become anxious. Due to anxiety a person feels tingling and numbness sensation as well as hot/cold waves at soles and palm. This is happening with you. I suggest you to relax and take it easy as this happens with every man. Hope it answers your query. All the best.
