A childhood belief about reproduction

I didn't really know how babies came to be; I did think kissing, hugging, hand holding, and making goofy eyes at one another had something to do with it. I thought that the state of marriage automatically meant a women would "get with child". It wasn't until 7th grade during a special presentation about human reproduction (for which mom had to give permission) that it all came together. The explanation of the sperm and egg fertilization made sense when a cartoon depiction (no details, side view of a male body) of a man who began to get an erection! I still didn't understand why blood would go to the penis or how. I was so grossed out at the thought of my mom and dad engaging in such an act. I vowed not to let that happen to me. I was very naive and sappy about love. Needless to say, I out grew those childish feelings and ideas.
