I think you got into some wrong exercise or techniques which is lowering your erection and i think due to wrong exercise i think the blood flow to penile chamber has been affected. I think kegel exercise would help you. or stop doing exercise for a while.
If you want to improve erection or sex drive i would say kegel exercise would help you.
