I love my husband waking me up with an erection in the morning. Sometimes it turns into a quicky before we both have to rush off to work, sometimes he just masturbates while I watch and get very horny! (Then I'm in for a treat that night!!!) For a nice long, slow session, late evening is always best. Kids fast asleep, (or preferably at grandmas!) candles, wine, massaging...
I also love day time outdoor sex. Fast, furious and so exciting.
