pain after sexy time

Who knows
Okay so I literally had sex maybe half hour to an hour ago.. He was a pretty big size... Just above average. 
My ex is just below average. 
Last time I had sex was 6 months ago. 
When I lost my virginity it didn't hurt so would it be plausible to think that I didn't break my Heman or whatever it's called with my ex but I did today...?
