if anyone can answer this for me that would be great.

my boyfriend and i have been having sex for a year now. we have used a very lasting variety of condoms.

just recently we started using Durex condoms. at first nothing was wrong with them. then as we used them more and more they started to irritate me. (nothing to him). they made me dry and uncomfortable.
now in the past week i have been feeling a itching/burning sensation around and in my vagina.

does this have anything to do with the latex in Durex condoms or possibly the lube?
