you are only supposed to go for a pap smear when u are sexually active.
so i think your mum might have a good idea that you have had sex if you told her you are going for a pap smear.
in my opinion, participating in a sport or activity they are passionate about doesn't make someone gay or straight. they might just love it. thats like asking.. Does playing tackle footy make a girl a lesbian?
no, it doesnt.
