Hi there ~ I understand your concerns. It seems like you have used over the counter medications for sexual enhancement and pleasure. The side effects of these medications are not known and therefore I suggest that you do adequate research before you try something that could potentially hurt your body. there are many medications that can help with erectile dysfunction, premature ejaculation and methods to use to enhance sexual pleasure. Please consult an expert in the field, who could be a local doctor, a qualified psychiatrist or a sexologist who can help with taking a history, an examination, required investigations if any including imaging as well as advising you with the right medications and counseling. I hope this helps. Take care and have a lovely day!
