What could it bešŸ§

I recently hooked up with a guy that knew for years. He said he waited for thatā€™s moment for 5years. He finished fast both rounds, that didnā€™t really worry me I am sure is probably was to excited. The entire night and thatā€™s days and events leading up to it he was so sweet and caring. After we had sex he went distant what does that mean?
