So after all these years, it finally happened for first time and didnt stop happening!!
I met someone on weekend and both had a drink and things happened unexpectedly.
Loved every minute of it at the time but I’ve been in pain down below since then. Feel like I’ve been punched! 
anyone else had this?
Was he particularly on the large side? Could be you have had your cervix bruised and can be painful for a few days afterwards. If it goes on for longer than a few days i would suggest you get checked out by your gp or possibly the sexual health clinic.
Sorry should of specified - was only from his handy work and oral. No PIV
Unless he fisted you then i cant imagine what could be causing it. Still if it continues you should get yourself checked out.
Was he a bit rough with the fingers getting you to squirt, could be soreness from that if so?
Might need to get yourself checked over just to be on the safe side.
This happened with my wife when we tried squirting before. I would go too rough like in porn, she was tender for a few days.
Now she knows and rathers it slow and steady to squirt.
Think may just be this to be honest
Once it happened, I didnt want it to stop and it didnt!
Im just suffering now. Doubt I will see him anytime soon so plenty of time to recover I suppose 
It is pain or an ache? I have no medical basis, rather anecdotal info, but could it be muscle ache. There can be pushing/bearing down when squirting so if your muscles aren’t used to it perhaps that’s why.
Not sure if you are referring to similar pain, but during various times trying, the following day I felt like I’d done a few sit ups, it was like a muscle pain and yes tender around g spot, went away reasonably quickly.
Congrats by the way on the 
Congrats on your successful squirting! Maybe take some rest time down there to recover!
I had had “complaints” post squirting of soreness but tends to go after a couple of days. Usually if i haven’t recently cut my nails or I’ve been a little rough.
Congrats non the less, hope it doesnt put you off.
