In the past few months my boyfriend has been saying how I feel a little looser than normal. I was a little peeved at his comment but I want him to be satisfied! I would try to squeeze my PC muscles extra tight but I had a habit of holding my breathe while clenching and would get light headed and dizzy and once even threw up in my mouth a little from lack of oxygen! I finally decided to take my problem seriously and purchased the Serre stick tightening wand. IT TOTALLY WORKS!
