Weird After PE Session

Hi guys, I’m writing here after 1 day of my 3 PE workout. My penis look a little bigger when it is flaccid, but not all day. When I’ve done my 2nd PE session my libido was high cause I did not masturbate for days, the night first of it I get normal night woods and the day of my second PE session after some hours my penis was erected so I decided to masturbate. Now after 1 day off I have not night woods or complete erections. Can it depend on my libido? I do simple roitine of 5 mins of bendages 5 min of stretching and 20 jelqs
