I'm sure I've read about this on this sub before but searches aren't coming up much use.

My girlfriend (f) and I (m) tried DP (with me and a dildo) for the second time at the weekend. We'd been having some sort of sexy time or another for a couple of hours by this point - regardless, I didn't last very long because it's so intense.

To finish my partner off, she had the vixskin outlaw inside her while I manually went about her clit. The build up was insane and she says that she's never had an orgasm like that before. I asked later if she was pressing against anything inside while she used the outlaw - she says no, just the all around pressure was delicious.

To my question... today is the first proper hangover free day for us, but she is more down than she's been in a good while.

Can anyone shed any light on the intense low after an intense high please?
