I'd be happy to hear any suggestions!
if possible make you able to do a full playthrough with only anal(no vaginal intercourse) both forced(grape) and consensual... maybe some kinda chastity belt that comes with buff and drawbacks... or some magic or some mechanic that lets you fight them off(as long as you are a virgin) as they try to enter you(vaginal with the excuse that hymen provides penetration protection lol)
