High sex drive

So I’ve been knowing my fiancé since child hood he’s had a thing for me since about 2015 and always told me I would be his wife and he loved me well 2017 of August we had a Netflix and chill night and he hasn’t left well he proposed shortly after and things have been great but the sex is a bit much he has LOTS of stamina and sex can go on for hours or until I give up we are trying to conceive any tips and tricks on how to speed sex up to get the baby juice faster because I’m tired of getting sexed till I’m dry 🤔🧐🤷🏾‍♀️
