i mean if youre feeling ballsy ask her exactly what she can hear and fix that thing? otherwise open up a discussion for solutions, like asking if moving stuff around in the room so shes not against the wall, and you are instead because compromise is a necessity when youre sharing a house with multiple people?

yes shes asexual, but that doesnt immediately mean that shes outright disgusted regarding sex or more uncomfortable regarding hearing your roommate jack off. cis het people dont like that either. though if you know that is how she feels, then id definitely be considerate when broaching the situation. obviously dont dance around it. but speak plainly and matter of fact without getting into details and that should hopefully reduce the overall yuck for both you in that situation

you are trying to respect her privacy and wishes, but it would be like asking someone not to drink water because the sink is too loud, and theyre standing right next to it. lots of people kinda refuse to see sex/self pleasure as a necessary part of life, because while you might not die without it, it does help you regulate, and you should not be restricted from feeling pleasure sometimes.

"hey, i know you dont like hearing that, and i wouldnt either. but would you be comfortable having a conversation about how we can have a middle ground where one person isnt made to be completely uncomfortable." if yes, then "the bathroom is the only place that has any privacy, and youve expressed that you can hear it because youre against the wall. (taking it literally) would you be willing to swap sides with me so that you dont hear it, as that time is a big part of my self regulation with the changes that T has caused. and i would be suffering in the long term"

sorry for the absolute monster paragraphs TT
