Adult circumcision messed up sensations

I got circumcised in my early 30s (2 years ago) due to a foreskin retraction issue and since the circumcision, Iโ€™ve lost almost all of the sensitivity on the head of my penis.

I can get hard but can never feel any touch on the head. Consequently, the time my penis stays erect went down drastically and orgasms arenโ€™t as strong or pleasurable as before.

Any tips to improve this?

Note:

  1. Heavy masturbator (min. once/day)
  2. Watched porn since mid teens
  3. Only got into a relationship last year - in my early 30s - a little after the circumcision (both events unrelated :sweat_smile:)

These notes are to give context to my issue
