According to a recent study semen allergy can make sex undesirable for women.

This type of allergy is usually treated by identifying which of the proteins in the man's semen are causing the woman's allergic reaction, then using a desensitization process to build up tolerance.
According to seminalplasmaallergy.org, a site that is maintained by Bernstein, people suffering from seminal plasma hypersensitivity may experience any or all of the following symptoms up to 60 minutes after intercourse: hives, soft tissue swelling, chest tightness, shortness of breath, wheezing, diarrhea, dizziness or loss of consciousness.
More common causes of skin and tissue irritation from sex include sensitivity to latex in condoms or the chemicals used in spermicides, lubricants or other personal care products.
