Is it permanent?
The odd of having sexual side effects from topical minoxidil should be very, very low. Erectile dysfunction wasn't a side effect reported in the large clinical studies from the 80s. Some blood pressure medications can cause impotence, however, topical minoxidil souldn't affect very much your blood pressure.
There are more probable reasons why someone may have impotence or other sexual problems. I think you should look into other factors in your life that may explain your concerns.
