I 22M and circumsized have noticed when I masturbate that I tend to hardly ever include the tip or the glands of my penis. The few times ive tried I have had to use a good amount of lube for it to be somewhat pleasurable. The sensitivity feel more like discomfort and almost like a burn in a away. When I do include the tip and use lube I use a loose grip but I still feel discomfort. Do I just need to continue to masturbate like this since I havent much prior or am I doing something wrong?
