I have been sexually active for 4 years. Today i was having sex with my new girlfriend for the first time and i realized that my penis would go numb during intercourse and it felt so uncomfortable that i had to take it out, and as soon as i did that the numbness would go away. Then when i start again i would feel okay for few seconds but again the numbness would hit back. What could possibly be wrong? I haven't had this problem ever in my life and i dont feel numbed when i masturbate. Its hard for me to explain the feeling but it could be best described as numbness. I could feel it it wasnt completely numbed, it just felt like its burning, or its like asleep, you know how your hands sometimes feel asleep? something like that
