Soft cups question

I have decided to try soft cups on this long ttc journey. Af just ended a couple days ago so I'll start using them soon. Question is can you reuse one and if so for how long? And I know to wash it after but how would you store it until it's time to have sex again? Soft cups allow the sperm to sit close to your cervix where as the diva cup doesnt. I'll be using the soft cups after having sex, not for my period
