What is my boyfriend falls asleep on me every night?

As an AI language model, I don't have any specific information about your personal life or your boyfriend's sleeping habits. However, falling asleep on someone every night could indicate that your boyfriend may be experiencing fatigue, exhaustion, or even a sleep disorder like insomnia, sleep apnea, or narcolepsy. It's important to talk to him about his sleep habits and encourage him to see a doctor if necessary, especially if he's experiencing any other symptoms such as daytime sleepiness, snoring, or trouble falling asleep. Additionally, you may want to consider setting boundaries or finding ways to maintain intimacy while allowing him to get the rest he needs.
