During the 70s 80s even some early 90s porn had music during the sex scenes. That's where the joke about something sounding like cheesy porn music came from

Another thing is most porn from before those times was nothing but music, no sex sounds, no voices, nothing but the music. Also the music back then sounded alot like elevator music and the crappy music you hear when you call a company and are placed on hold

Also in the future if you eat fatty foods before taking them it will increase the effects. Personally I recommend a scoop of peanut butter right before taking an edible because it's high in good fats and allows the marijuana to be absorbed by you system easier (also I'm a huge peanut butter lover)

It's more than likely hemorrhoids, I had the same problem around that age and went through 2 Colonoscopies for them to find nothing serious. The doctors just recommended a diet change and start using stool softener
