Birthdays

Does anyone one have an opinion on the idea of giving sex for a birthday present? Like the song! I have no idea what to get my bf for his 21st and I'm only 20 so I can't take him out anywhere but I was thinking like a day in bed with planed events wouldn't be a terrible present ? Right? Any ideas ? Please help!!! He keeps telling me he doesn't need or want a thing from me 😡
