"Sex Talk"

My mom has always been the one to give me "the talks." My dad tried once to give me a talk and it was all bad. I remember it was before I went to prom my sophomore year. I didn't have a date necessarily or anything because it's a junior-senior prom. My friend didn't have a date either so she invited me to go with her. Either way I wasn't going with a guy. My dad had it stuck in his head that since I'm going to prom I had to be going with a guy.
My dad decided to take me out to eat one day, which was very strange. Since I don't live with my dad I only see him on holidays or when something dealt with sports in my life. Because he wanted to take me out to eat, I knew something was wrong. He started off the conversation joking around with me about if wanted to order a limo for prom and all that stuff, then things went bad. He said, "Prom is such a cliche thing." I already knew where he was going. He started saying, "When I guy thinks your pretty, he'll be real sweet and ask you to go to things like prom and such." He then said, "And after a guy is real sweet, he's gonna want you to be sweet in return." I practically threw up in my mouth. I wasn't sexually active at the time, and to think my dad was trying to give me the "talk" just grossed me out.
He started saying how "giving it up" on prom was cliche and I would regret it for the rest of my life. He is so bad at things like that and it was so awkward. It took me a while to even think about sex again because every time I tried to I pictured my dad.
