My age is 24. I have penis with tight foreskin where I cannot able to pull back and even it's hard to get it retract to normal position over the gland. I can comfortably do masturbation while doing sex I am unable to enter inside vagina in return I am getting blood by tearing tissue beneath the gland. Also my penis is getting loose just before entering inside the vagina. I used to clean the white layer regularly under the foreskin but the issue still exists... kindly suggest me the best treatment for this.
