Regarding erectile dysfunction. Plan!

Hello Doctor, I am 30, married, and have been experiencing erectile dysfunction. I can usually get an erection during foreplay, but after some time it becomes weaker. Sometimes I get a decent erection and suddenly lose it when we are about to have intercourse, making penetration difficult. My erection quality varies. I have a history of frequent masturbation for many years and previously frequent pornography use, and I want to know whether this could be contributing. I am also concerned about pelvic-floor issues, hormones or blood flow. My wife and I are trying to conceive. My semen analysis showed good count and motility, with morphology 3%. I have previously taken Procibel-M and was given Megalis-10 (tadalafil 10 mg). Please evaluate the cause of my ED and advise whether I need blood/hormone tests, whether tadalafil is appropriate while trying to conceive, and whether I should continue Kegel exercises. I want a proper diagnosis and treatment plan
