I’m 45, soon to be 46.
Regular, but not daily, excellent morning wood.
Regular nightly excellent wood (getting up to pee in the small hours of the morning—thank you middle age).
Erections no longer always available on demand, but much easier in the morning due to testosterone level peak at that time of the day.
Too soon to determine if PE changes EQ as I’ve only started.
Am doing PE as an adjunct to foreskin restoration. Being cut has led to major sensation loss, which has likely contributed to sexual performance, although I still mostly credit normal middle age body changes.
