No one likes getting tested for sexually transmitted infections (STIs). You have to talk about your sex life with a stranger. (Or, worse, the same health care provider your mom goes to.) You have to make time for, schedule, and go to an appointment. Then you have to have swabs and/or blood taken, neither of which is at the top of anyone’s “fun things to do” list. But in the age of telemedicine, a few companies are making it easier than ever to get tested.
