Among men who have anal sex with other men, the partner who inserts his penis may be referred to as the top, the one being penetrated may be referred to as the bottom, and those who enjoy either role may be referred to as versatile.[7] When MSM engage in anal sex without using a condom, this is referred to as bareback sex. Pleasure, pain, or both may accompany anal sex. While the nerve endings in the anus can provide pleasurable feelings, an orgasm may be achieved through receptive anal penetration by indirect stimulation of the prostate.[8][9]
The release of testosterone is regulated by luteinizing hormone (LH) from the anterior pituitary gland. Sperm production is controlled by follicle-stimulating hormone (FSH) from the anterior pituitary gland and by testosterone produced within the gonads.
