How did it feel to see a guy naked for the first time?

Would be interested to hear about how people saw a guy naked for the first time. Was it your ultimate long-term partner? What did you think? Was it what you expected? Did you see it hard? Did you proceed to do anything? Personally, it was my long-term boyfriend for me at 21 and I actually felt quite shy and nervous. I saw him get erect and it was quite amazing I thought. Did anyone else feel the same way?
