Hi joycejoy – it’s hard to say because it happens differently for different women. I can’t personally remember my hymen tearing (although i suspect it was when I was under anesthesia receiving a pap smear) but other women have their hymens tear in the course of doing vigorous activities like horseback riding or playing sports. Others have it tear when they first have intercourse (which is part of why we have a cultural script about a woman’s first time being painful) but I think it really ranges between people. Your hymen may end up tearing before you’re even sexually active depending on what kinds of sports and activities you do. Hope that helps!
