I have athletes foot and i took a shower where people have intercourse if i step on semen can i get hiv?

Very unlikely: Even if the people having intercourse and shedding semen on the floor have HIV, it is not likely to infect a person with athletes foot or without such affliction. Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
