Can stress affect a man’s sexual interest?

My boyfriend of three years have had our ups and downs, he’s stuck by my side. He’s a nice guy who avoids conflict and is an over thinker. So in the relationship I dominate in sex because he always wait for me to initiate or anything, at times he will initiate. We don’t get a lot of privacy but we see one another every weekend and we always have sex or I give him head. This weekend we hung out and work has been stressing him out I mean he’s been upset and his entire mood has been affected due to the situation. He vented to me what happened and was upset so the mood was changed but I supported him so we took care of business and watched a long movie at the theaters afterwards he was tired and it was cold and raining and he said he was gonna head home. I asked him if he wanted to do anything else he said no he wants to head home now. I thought okay he didn’t ask but I know he’s tired and stressed. He’s affectionate bought me flowers, holds my hand during the movie. He’s 29 year old male is this normal?
