First of all, congratulations on all your hard work!! You are being so persistent!!
As for the tightness after an orgasm, if your muscles are tightening, maybe you should dilate afterwards. I personally haven’t experienced this but since you have some time before your next appointment, you could see if dilation makes a difference! If you are sore after you could put a warm compress down there or even a cold one! I’ve done both and they have both been very effective in relieving the muscle sorness.
