I would agree with last two comments - believe me, you spend half their life trying to get them to stay in bed and the other half trying to get them out of bed!!
Only other thing is, and not to scare you, you may find that you have to return him to be LOADS of times even up to 70 or 80 the first night BUT they will get less and less. I don't say this to frighten you only to point out that although it seems useless, it will work and you must persevere. You are not alone - think we have all been there. The ones who did not keep at it still have 6YO's in their marital beds!!
