...friend that I had sex with? This might sound a little strange, but it's been bugging me. At school we have to wear polo shirts as part of our uniform. Until recently I've always worn mine with the top button done up and have hated leaving my polo unbuttoned. Lately I've been wanting to "experiment" with girls and I managed to get up the courage the other day to ask one of my friends how they felt about girls. Anyway, long story short, we had lesbian sex and I really enjoyed it, but since then whenever I'm around her in my school uniform I've always unbuttoned my polo without even thinking. Is there a reason that I've preferred to unbutton my polo shirt around her since we had sex?
