one's own parents do not count
i've had young, attractive couple have passionate, long (45-50 minutes intercourses maximu, minimum 15-20 was the length of their intercourses while I have lifelong PE) sex above me even 3 times a day (normally 3-7 times a week, sometimes 2 times a day, usually after sex day there was 2-3 days of no sex and longer pause during periods). now above me lives a single man again, like is usually the case there and in most other apartments in this building also. i have also heard sex from below a few times, but very infrequently. from above my bedroom all the bed sounds can be heard very clearly. i hear everytime one enters and exits the bed (not related to sex usually. i hear movement and steps above. i hear when one vacuum-cleans, opens things (i don't know the word for it), takes a piss/shit/shower above and below me and in the neighbouring apartment on my level also.
now i haven't heard any real sex for a long time, big reason i have not been very depressed lately.
it is crushing to hear and healing takes time and i will never heal fully from what i have heard in the past. i have even heard "I love you" during sexual intercourse. i have heard the lovely woman who used to live above me wake her man in the morning. i once heard long blowjob while lying on my bed. i was wondering what that sound was, no movement sounds, no bed creaking sounds, no woman moaning, i only was fully sure after the man ejaculated and moaned at the end. and it lasted like an hour or so, i don't recall now how long it was and probably i did not hear it from the beginning. i think the man had the opposite of PE, delayed ejaculation. the woman ALWAYS got her orgasm before the man came, usually multiple orgasms. 3 was the normal orgasm count for the woman during intercourse before the man ejaculated.
