How to get my sister to stop freaking out about being pregnant?

well she’s my sis and she’s been honest with me I know cause she’s never had a boyfriend and our parents NEVER allow guys to be alone with us just to prevent such things. I mean even when I tell her if no sperm has been near her she’s ok. I tried talking to her tonight and think I found the problem. her a group of her girl friends were playing a game of truth or dare. well one of them decided to do a “group” dare where everyone did the dare. and they agreed. the dare was each one had to hump a pillow just for laughs. well I think she thinks by humping a pillow she had sex and there’s a chance she’s pregnant. I was like amber… there’s NO possible way that can happen! your NOT pregnant! you need sperm to get you pregnant. and I think I might of got through to her cause she said thanks.. you made some sense I think.

so did I do good by telling her that?

ok first off this is annonomus now… lol that’s funny I mean my friend always tells me what her sis is doing and I’m like omg are you serious?! lol

You seriously should just buy her a bunch of pregnancy tests.(hey sisters gotta bust on eachother sometimes right?)

Have her take a test if she still is worried… hopefully that will knock some sense into her and get it through to her that you cannot get pregnant by humping a pillow.

Make her watch the discovery channel or something. LOL
