Last night was incredible to say the least. We used my packer as a stand in for some hand action, then I attempted to use a strap on. Problem was it either wasn't long enough, or we couldn't get the right angle no matter which position we tried. I'm not sure if this has to do with my weight ( I'm 267lbs) or their height and my height difference ( over a foot) or simply too small of a strap. I have also been the submissive one in past relationships and been definitely more dominant here but still learning. Any tips, advice?

Please be kind as this was our first time after being together a year and the fact that they opened up enough to try is huge progress. Plus, no fat shaming!
