I've gained loads of fat in the past 18 months due to the lifestyle i've had and i've only just started to shed it off. One thing i'm looking forward to is gaining back ~an inch of my penis from the fat around bottom, and i can finally be average size again. After the weight gain, I've also noticed it being more difficult to get fully hard erections; the head of my penis is smaller and the colour of it is pinkish and not reddish-purple as it should be. The veins in my shaft don't show much either. Anybody else been affected by weight loss & gain?
