Kinky sex ideas ???

Lately me and my partner have both been interested in trying new things in the bedroom. We're open to lots of bed ideas of things to try but having trouble finding ideas on the internet. My question is what have you done/done to your partner which is a bit weird but you enjoyed it? He's been interested in impact play for him (hitting etc his dick/balls) and has been interested in putting things inside me. (I'm usually a very shy person during sex so this is all very new to me.) But I want to hear your suggestions!
