I had gynecomastia from about age 12 to 20 when I had surgery. Its better now than it was but still not perfect since there is some scar tissue in place of the gland/tissue/fat that was there. I haven't read anything about titty twisters causing gynecomastia but I think there could be some relationship between the two. When I was in middle school I had a friend who was a year older than me and he used to give me damn twisters all the time, his older brother gave them to him also. I remember my breasts hurting a lot for awhile and I think the twisters affected the natural maturation process of puberty. The kid who did this also had some serious man boobs. When I think back to it I want to punch him right in the face the first time he did it so it never happened again but I didn't and he must have given me a hundred breast twists- not to mention other random people who did it. If someone ever gives you one I think you ought to punch them as hard as you can right in the chin, or maybe across the nose so they have a crooked nose for the rest of their life. Thats all!
