Confused...

si

Ok so me an this guy I've knew for a while got a job working with me a few months back an 2 or 3 weeks ago we started hangin out an we've been inseparable ever since. But back to the point we've had great sex like best mind blowing sex I've had he makes every hair old my body stand up. But he recently he's had some trouble keeping it up if u know what I mean. Usually sex kinda hurts where he's rather gifted. But idk I feel like it's me but I've always had self esteem issues. He swears up An down it's not me. That he's just got a lot on his mind which his dog got run over An he's had to fork out a shit ton of money for him An he's been broke which I've left 20 to 40 bucks laying around his house because he won't take money from me. Idk am I over thinking this or is he right???
