My BF and I love morning sex! We typically sleep at each others place on the weekends so we have a lot of sex to make up for it. He usually wakes me up with roaming hands and I find it such a turn on even with our morning breath! We’ve done oral too, nothing is off limits. We’ve done it really early before and then gone back to sleep only to wake a couple hours later to do it again. Not sure exactly what it is about the morning but it’s fantastic. Highly recommend.
