I get red, swollen, sore and increase in vaginal discharge after having sex with husband. no use of condom/lub. is this a reaction to his semen?

Semen Allergy?: Semen allergy is a real but very uncommon disorder. Here is a bundle of links about the disorder (http://bitly.Com/xy91t2). Your symptoms sound like you could have the problem. There does seem to be treatment but you need a specialist to cure the problem. The disorder is often not recognized so you may need to get help from someone who is familiar enough with the disorder. Good luck.
