Curiosity About Seeing A Penis

I have never shared this with anyone. When I was 18, I'd only had one boyfriend, but not serious. I'm not shy, weird, or ugly. I've won beauty pageants, I can dance and sing, and focused mostly on school and my friends. Boys weren't a focus point. But I became curious about seeing a man nude in person. My step-father had been in my life since I was 8, and even though I thought of him as my real dad, I always found him attractive. He was mid-40s, athletic, and muscular. One day I came home early from school and heard the shower running. When I passed by their bedroom, I slightly opened to door and saw the bathroom door open. I peeked around the door, but he was not standing in front of the etched glass door where I could see him. I decided to yell his name and ask if I had left my shampoo and conditioner in their shower (I knew I had). He answered back and said it was in there. The glass was fogged over a bit, and I could barely make out anything. Two towels dr**ed across the top of the door blocking his chest and face. I asked if he could hand them to me over the door. As he stepped next to the glass to hand it over, I could see his cock with very little obstruction from the etched glass. It was longer and bigger than i woukd have imagined, but had no others to compare it with. My heart began to race, but I stepped in and walked over to get the bottles. I was so frazzled, I placed the bottles in my bathroom and forgot to fake a shower. I wondered if he realized that I had intentionally done that to see him.

I could not stop thinking about it or him afterward. About a month later I had been in our tanning bed and I heard him on the phone coming up the stairs from the basement. I decided to step out completely naked and let him see me and I timed it where we would meet in the hallway. I acted shocked but didn't cover up. I saw his eyes go up and down and I said "I'm sorry I didn't think anyone was home." He didn't act embarrassed and said "It's okay. Don't worry about it."

Over the last 4 years, I've intentionally walked into their bedroom without knocking and seen him naked several times - once he was semi-erect. I want to see it fully erect at some point. Now I have a boyfriend and we have sex but his cock isn't anywhere near as big my step father's.
