Bf not dirty after work

This is gonna sound bad but I have trust issues and he's broken my trust before .

I've noticed when I shower with my bf after He works sometimes he doesn't stink, barely washes his body. Just pits and privates.

However he works outside I'm the woods for around 10 hours. Sometimes it's light work sometimes it's hard work. When he use to get here he would smell like sweat and dirt. now he hasn't been for the past few weeks. It's been almost 80s-90s so I don't see how he's not sweating. ???

I asked him about it and he said he hasn't been showering anywhere else.

Am I being to parinoid?
