When we first began dating and we were only seeing one another once every two weeks at the most, sometimes just once a month, our usual weekend looked something like this: say hello, eat, go out someplace for 2-3 hours, fuck, cuddle, fuck, sleep, wake, cuddle, fuck, cuddle, shower/fuck, eat, fuck, cuddle, fuck, cuddle, shower/fuck, eat, go out someplace for 2-3 hours, fuck, cuddle, fuck, sleep, fuck, cuddle, shower/fuck, eat, go out someplace for 2-3 hours, fuck, cuddle, fuck, shower/fuck, eat, say goodbye. (I read this out loud to TheBF just now and he's of the opinion that I'm vastly over-estimating how much time we spent going out.) From my experience, that's pretty usual during the honeymoon period of a relationship.
TheBF can cum and just keep on fucking. He especially does it when we're having anal sex, because he loves it so much that he just doesn't want to stop, and he won't stop until I have cum, too. He also has a rather fast refractory period most of the time, but he often doesn't push for a second time because he worries that he's being too greedy or I'll get too sore or that I'll just acquiesce in order to satisfy him because he often assumes that I'm just being really nice to him. He often doesn't realize that I like it when he's greedy and he really isn't imposing his will on me. I'm really not just being nice. I want him.
We go through periods of being like cats in heat where we'll have sex multiple times a day for several days, or even a week, but then work or exhaustion or other things in our lives interfere and a week will go by when the precious down time that he has is mostly spent asleep or reconnecting with me socially and emotionally rather than sexually.
