Dating a friend…

I’ve been friends with this guy for over 20 years, we grew up in the same friend circle and just got closer as time went on. We never really hung out one on one but we would always check in through text. Well back in November we saw each other in person and I felt a switch, I was attracted to him. I never felt that before and It was always just a friendship where we could talk about anything and be ourselves. I let the feeling go without action but this past weekend we saw each other again and felt the same way. So my friend said something to him and he said he never really thought about It because we have always been platonic friends so his mind just didn’t go there but he wanted to explore It so we are just talking. I have no clue where It will go, if anywhere but what’s weird to me is how you make the physical switch and intimacy. It’s seems like It will be so weird and uncomfortable. I’d love anything advice, thanks!!
