Male sexual organ is composed by 10 different main parts. Going from the inside and invisible parts to the outside, we find the bladder, which is connected to the urethra (the little tube through which pee and sperm come out), the prostate gland (in charge of producing a fluid that protects sperm from the acid reaction of the vagina but also a pleasurable area) and the seminal vescicles (the producer of seminal liquid). This last one is connected, through the vas deferent, with the testicles so that, through the vas deferent, sperm is carried to the seminal vescicles. Among the visible parts of male sexual organ we find the foreskin protecting the gland -in non circumcise penis – and the gland, the most sensitive part of the penis, with 4000 nerves and, of course, the scrotum. The penis is composed by two different areas: the corpo cavernosum, a spongy tissue carrying the blood that allows the erection, and the corpus spongiosum, in charge of protecting the urethra and preventing it from closing when ejaculation is needed. Beside the anatomical structure, men are capable of reaching three different kind of erection: reflexogenic -through direct physical stimulation-, psychogenic -thanks to fantasies or audio/video stimuli- and the nocturnal erections -happening during sleep circle even 4-5 times per night-. In terms of pleasure points for men, beside the gland area, the stimulation of the so called P Spot, the prostate area, can be very pleasurable. The P Spot is located 2in inside the anus, on the front rectal wall.
