How do I know if cum? 🤦🏻‍♀️ (posted elsewhere also!)

So basically.. I’m 26 and have a high sex drive! I always want him, he on the other hand is a once a week kind of man, and as much as I’m always down for it, and thoroughly enjoy him he only lasts about 30seconds sometimes a little longer if I’m lucky 🤦🏻‍♀️ I end up so frustrated because I’ve waited so long for him for it to be over before it starts.

If we’re having sex, there’s always loads of wetness from me, and after there’s always white creamy stuff.. but how do I actually know if I have cum? Is that all it is? Just the white stuff?

we have sex toys and stuff and he’s explained the one fantasy he has is a women to squirt for him but I just can’t? Is this something I can teach myself or not?

I feel like maybe I’m not sexually satisfying him and the reason he goes so quick is to get it over with.

Am I being stupid or just need to ignore it?
