When you kegel you're flexing all the muscles near your perineum. The two most most referred to muscles are the PC (Pubococcygeus muscle) and BS (Bulbospongiosus muscle) which encompass such benefits as increased sexual function (erection quality, premature ejaculation), preventing urinary incontinence, and treating BPH (benign prostatic hyperplasia) inflammation and pain.
The two muscle we refer to (PC and BS) are commonly mistaken for being synonymous, and although most men target both muscles when doing kegels, they are very separate. The anatomy of the PC muscle originates from the back of the pubis, and is mainly responsible for controlling urine flow and contractions during orgasms, extending backward and horizontally along the anal canal toward the coccyx.
The BS is a superficial muscle that originates from, colloquially, "the taint to the tip". The BS is responsible for emptying the urethra in men, and the middle fibrous portion of the muscle forms a sheath around the bulb of the penis, also referred to as perineal raphe (taint to tip), and parts of the CC; anterior and longitudinal.
When kegeling try and focus on the BS muscle because it is clinically linked to the "hard/flaccid" state, which is a chronic soft erection, known as Venogenic Erectile Dysfunction and Penile Venous Insufficiency. The cause of the condition is still unknown, however it's believed that it's due to lack of sufficient arterial blood flow through the cavernosal arteries of the artery, which affects the drainage of the cavernosal tissue of the penis, allowing for a "leakiness". It's been speculated that the defect resides in the connective tissue of the tunica albuginea surrounding the Deep Dorsal Vein of the penis. It's important to remember that unlike the middle fibers of the fibrous (BS) muscle, the anterior fibers contribute to the erection of the penis by compressing the deep dorsal vein of the penis.
In other words. When you kegel, try and focus on the BS for better erections. This is my non-vague answer.
