Symptoms don't always appear, but if you've had unprotected sex, you're both exposed. As long as you're single, I advise condoms. Experiment until you find one brand that works best for you. Some intact guys like those with more headroom to allow the foreskin to glide back and forth. Others like more restriction. Does your foreskin tend to glide or does it lock behind the groove? What is it you don't like about condoms?
