How many times per week do you ejaculate?
Ejaculation is associated with increased prolactin levels. Prolactin may be the cause of your puffy nipples. Of course, there may be other causes associated... But you could limit ejaculation to once per week to help reduce prolactin levels. Using this method of ejaculation control you would also achieve higher levels of testosterone, which would be beneficial to your puffy nipples. Gyno can be stimulated through lack of androgens. Testosterone is androgenic and would also aid you in your quest.
Lifestyle choices can be a major player in puffy nipples. Drugs and alcohol are said to play a role in gyno.
Supplements can help reduce puffy nipples as well. Try P5P (b6 coenzyme).
