It's just... wrong... You are suggesting - Log in, go to sleep, log off, watch porn, log in, get XP bonus, log off, watch porn and so on. I just do not like this. If the XP bonus will be big, people will find caps no matter out of where, just to sleep and gain experience. If the XP bonus is small, none uses it. I do preffer the healing idea though, you should be able to get out of the bed anytime tho, incase your gang needs emergency back-up.
