Q: My story is about a woman who, for various reasons, does not want to have sex with her husband. She decides to obtain an antiandrogen drug and administer to hubby sub rosa to prevent him from having erections. What drug might be best for this? How would it be administered? Could it be obtained from foreign pharmacy in Canada or Mexico?

A: There are many drugs that can potentially cause impotence or erectile dysfunction. Most are unpredictable and they work in different manners but since she would have access to his food and drink and even his medications on a daily basis she could easily perform a trial and error study to see which ones work best for her needs.
One would be simply giving him her birth control pills. These would be easy to crush and add the food and over time could cause an elevation of estrogen and a lowering of testosterone levels and this could interfere with his sexual function. This would take weeks or months to work and he could have certain side effects such as slight breast enlargement and tenderness but for the most part the drug would go unnoticed he would simply have a more difficult time getting and maintaining an erection.
Many classes of blood pressure medications can do the same thing. Diuretics, ace inhibitors, and calcium channel blockers can do this but by far the most likely are the beta blockers: atenolol, metoprolol, and propranolol are the most common. These drugs tend to lower the blood pressure and slow the heart rate and this is how they lower blood pressure but they are also notorious for causing sexual dysfunction in men. Besides the sexual problems the other side effects that he could experience would be fatigue, sleepiness, forgetfulness, and possibly some shortness of breath. In most people these latter symptoms are mild and he might simply write them off to being overworked or under stress as these symptoms are also associated with that.
The medications used for prostate cancer such as Flutamide and Leuprolide, can also cause impotence.
HERE is a useful chart of the drugs that can cause sexual dysfunction.
Each of these medications is easy to obtain as they are very common and widely used. She could forge a prescription, steel some from a neighbor, or get them prescribed for herself. Many can be ordered from Canada if a valid or forged prescription is available. If she or someone she knew worked in a pharmacy or a medical facility they could easily be stolen as they are not controlled drugs and therefore not locked up and often accounting is lax.
Of all of these possibilities I would go with the beta blockers. The dosage can be adjusted up or down to cause a more or less affect on his sexual performance and also to lessen any side effects he might have. Each comes as a pill that can easily be crushed and added to food.
