Other things to check on that may be causing the problem is to ensure you are using the proper lubricant (such as
KY jelly) if the area you are entering is dry to avoid friction on the penis. If your partner uses douches, body sprays, or if you are using sexual body butters, or lotions or anything else that is scented it could contain colognes, perfumes, or alcohol, you could be having a reaction to them as well. If you are having sex too frequently this may be the cause.
