Gyno (NSFW) (Patreon)

When we watch porn together, I'm amazed that Joe can always tell if one actor is using steroids. And I did some search on Google, here's some explanation: 

Gynecomastia (commonly referred to as “gyno” or “bitch tits”) is the enlargement of the breast tissue in males. It can occur naturally in puberty or old age and results from an imbalance in estrogen action relative to androgen action at the breast tissue level. 

Steroid can increase the level of estrogen in the body which causes gyno. 

The symptoms of gyno are: swelling and tenderness of the nipples and breast tissue or itchiness of the nipples. If you experience these symptoms, treat them immediately! Once breast tissue forms, it is permanent! The only way to remove it is through plastic surgery.
