text: if ur boyfriend wears a condom will the doctor be able to see if yall have had sex? he always wear a condom before we have sex but my mom want to get me tested to see if i have had sex because she dont know i do well, the doctor can only know if the hymen is broken.  most frequently this is from sex, but not always.  there are various activities that will break your hymen that don't involve sex at all.  so while it's probable, it's not 100% accurate.
