>How much content is there if you lose a fight and get raped
Depends on the mods you run, there are simple defeat mods that will play a rape scene and let you continue with some debuffs and there are ones that have bigger consequences like enslavement or execution (also expanded for followers).
>Are there new quests that utilize the sexual content, were some vanilla quest also changed to fit in with the theme or are they the same?
Yes, there are mods specifically for sex ranging from lenghty plotlines with voiced NPCs and custom locations to just system based mods like radiant prostitution that work like Todds endless radiant quests.
Vanilla quests have expanded options like instead of having to steal an item or use persuation you can use seduction.
