Summarize the following:
If you need to shave, trim your nails or pluck your eyebrows, do it beforehand so that you don't waste time at his house. Have a discussion with your boyfriend before you sleep over as far as where you both are in your relationship physically. This will be different for everyone, but don't go through with a sleepover if you haven't set boundaries that you are both comfortable with. Deciding on boundaries beforehand will help you be prepared to handle any situations that could arise. Make sure you don't do anything at the boy's house that you would regret later. Be careful so that you don't get yourself in trouble or give yourself a bad reputation. If you're staying over on a school or work night, you want to make sure that you have enough time to get ready for the day. Waking up early also gives you an opportunity to do something sweet like make breakfast or write a cute thank-you note. If you have to leave early, make sure you say goodbye first. In case you need to leave early in the morning or decide you don't want to stay all night, come up with a plan. If something goes wrong, like he wants to move too quickly and physically than you're comfortable with or you're allergic to his pets, have a legitimate excuse. You could say that your parents need you to come home or that you're not feeling well. Don't be afraid to be honest and say that you need to go home. Honesty is still the best policy.
Take the time to clean up before sleeping over. Set boundaries beforehand. Wake up first. Have an exit plan.
