I’d say night sex if I had to pick. In the morning I get wood that seems to never end, which sounds fantastic, but it takes forever for me to cum, which isn’t so great.
There have been plenty of times in my life where I’ve just said – “ah fuck it. I guess we are done.” But I love 3am sex, which is not really morning sex. Midday is great too. I really don’t give a shit when.
