Dear …
Thank you for such a great __(day/evening)__. I really enjoyed __(our dinner together/bowling with you/etc.)__. You are so down-to-earth and I really like __(your sense of humor/the way you…/etc)__. Even though it was only our first date, I have to say that I felt very comfortable with you. In fact, I am going to step out even further and dare to say that I felt a bit of a connection with you.
I’m hoping that you too felt some chemistry between us. We seem to have quite a few things in common and laughing together comes easily. If you share these thoughts, I would love to have the chance to see you again to get to know you better.
Thanks again for the great date, __(Name)__. I do hope to hear from you soon!
Take care,
