Im a 19 year old uncircumcised male and have been masturbating by placing by hand over my penis, putting it in between my thighs, and applying pressure (it sound weird, i know) but i recently lost my virginity and felt no real sensation during sex, so after doing some research i decided to start masturbating normally, but when i do it feel no pleasure and can not orgasm should i be concerned or just keep trying till i start feeling pleasure?
