Basics of Sex

Some questions:

How old is he?
Does he seem to be enjoying himself otherwise?
Did anything else change three weeks ago? Say, did you switch birth control methods?
Do you have any other reason to think he might be losing interest?

Hi there,

I would suggest you probably stop overthinking it.

Perhaps try and get out of a routine a little....maybe the sheer fact that it is ready and available for him every night is what is taking the potency out o his oomph...

In my opinion he is perhaps getting very used to the sensations...moves, thrusts etc and thus perhaps he needs a little more touch stimulation or  a physical point of difference to get over the line. It could also be a matter of him being tired, fatigued, exhausted given the everyday sex routine.

Basics of Sex

I'm going to take a stab in the dark and say that he doesn't actually want sex every night and is only having it because the sexual relationship is new and fresh. If he had a choice, or rather his body had a choice, he would be happy with sex 4-5 times a week (perhaps less).

I think what you're seeing is that his body just can't cum or orgasm because he's been orgasming every night and his body just wants a break. Yes, you're sexy; Yes, he's enjoying the sex; Yes, you arouse him, but his body just can't quite get there and cum some nights....

Usually in a new relationship the sex starts with a hiss and a roar. You have lots of it all the time. After a while (which varies from couple to couple) the frequency reduces. You don't do it as much. Going well, you both have similar libidos and you both have sex often enough to keep the two of you happy but not so often you're getting worn out all the time.
