To list a few myself: I've only had very minor ones here and there through my teenage years, such as:

• a Cousin who looks like Alexandra Daddario. Need i say more. Luckily a very fleeting one.
• A milfy english teacher with heavy round boobs and really thick thighs. She was actually already married/dating an ex-student of hers, apparently. My grades skyrocketed in her class.
• As an adult, I wanted to have a threesome with a friends girlfriend, but i know that neither of them would be into that.
• Superior at my first job who had beautiful brown skin and wore sundresses a lot. Married.
