Hi! You can 100% get Azram's "good" ending if you choose not to be intimate with him. The intimacy, whether you've had it previously or want to have it during this last night, is purely flavour and does not affect if the ending is good, neutral, or bad in any way. This game was very intentionally created to be ace friendly because I wholeheartedly agree, a precedent where sex equals a good ending isn't a positive one :)
