So whats the deal?

Okay so a little backstory: myself (26 y o female) and my (27 y o male S. O) have been together for just over 6 months. At the start our bedroom time lasted around 45-1.5h but recently it lasts no longer than 10 minutes...

I'm probably over thinking this because I just watched a video that girls are apparently worried when a guy takes a while and im here worrie if im doing something wrong now... when he needs no longer than 10 mins.

So the question is why was it like that at the start? Why is it like that now? And is it a good thing or a bad thing he gets off quicker?

So whats the deal?
