Not sure how to spice things up

Kayla

Ok so not sure how to word this or if this will make sense to anyone... So for the past 3-4 day I've been extremely horny.. have wanted to try new things with my SO but to afraid to say something.. I've also wanted to have a couple with us in the bed room... also to afraid to say something.. this being said my SO hasn't wanted to have has much sex lately... he's 26 I'm 20.. idk if it's the age but he's just not as sexual as he use to be when we got together (have been together for almost 3yrs) when he does get horny or hard it doesn't last longer the 10mins or so. Don't get me wrong I love every second of it but 9times out 10 I don't finish but he does.. I just need some advice on what to do or what to play...
