My problem is related with Sex. I have erectile problem due to that facing problem in penetration since 3 years. I have consult with Sexologist but they told there is no any problem and suggested psychiatrist.

But now a days there is another problem, after taking such peels I am facing problem of heavy Headache, pain I legs, feel like hangover on next day. please suggest what to do.
