Could i have a latex allergy? i experience discomfort and a slight 'rawness' during and after intercourse despite using lube. no other symptoms. why?

Not allergy: You are describing a local irritation. You may need more foreplay, a different partner, better relaxation, much more lube. Tell your partner to be more gentle and go slower. Maybe a different brand of condom.

Possible: If you are using latex condoms----but certain lubracant--esp sented have potential allergic reactions as well as spermacide
