Update: We had sex and it was amazing! Appreciate all the comments.
I have a really small d and I’m insecure about that. I also have zero clue what I’m doing. I’ve never even kissed before. I have no confidence. And I’m generally just terrified of this experience. But I feel like I need to because I’m 30. Sure she is sexy and I bet it will feel good for me but I have no idea how to make it good for her because of my lack of experience and anxiety.
