Body doesnt want a second Round

So sometimes i cant stay hard during foreplay and when my gf and i want to start to have sex my penis often stays soft.
But when i can stay hard i come very fast because im too aroused because of the foreplay and i am exremly wet…

I always thought: yeah just go another round… but my issue is that when i come, my orgasm is so intense and there is always so much cum. After that my penis just dont want to get hard again and i feel like i need hours of breaks…

Is there a libido problem? I really dont know what to do here
