So I've been dating this guy for two months and we are both religious and believe in only having sex after committing to someone via marriage, so we're virgins. However we mess around plenty, and I finally got the nerve to unzip his pants and reach down there.. then afterwards I asked him, "wait are you wearing underwear??" to which he said no. He never wears it, but he swears he keeps very clean (probably true, he never smells bad or anything) and he always washes his pants after a day's use. I was like wtf that's just a larger amount of fabric you have to consistently wash! You hippie!
