A relationship with an older man

My dad has a friend.
He is gay and no one knows about that but me.
He has been flirting with me for a month or so. Then he saw that I gave him little resistance than before, and bought me things.
No one has given me such attention, and I felt comfortable around him.
This week, we were alone in my house after my dad left. He touched me, and I was a bit nervous. Then we had sex.
It is my first time, I had sex with a man. I am 22 and he is 61.
I dont know if to continue that relationship. I dont want to separate, I feel he understand me. He wants me to think of moving out to his house and live with him, because he feels lonely most of the time. I kind of want that.. but not sure.

What should I do?

Well seems as if that's up to you, what would you like?
