When I masturbate I have been noticing that - though I still get myself to climax - I have not been getting any sense of satisfaction or fulfilment. The other day (literally an all day event on one of my days off) I even masturbated on 8 different occasions ranging from finishing as quickly as possible to really long and drawn out "edging" sessions. Despite being physically completely done in after all of that I never got the usual sense of completion that I normally would. More recently than that I've noticed that I'm actually having trouble keeping myself fully erect when not directly stimulating myself in some way (didn't have that issue before). I can't think of why this is happening. I am no more stressed or any other psychological factor. I'm not lacking on sleep. I'm not disinterested in sex or sexual stimulation... Very confused and kind of concerned. Am I just overthinking things here?
