every muscle in your body is contracting?
Many muscles do contract when you orgasm — and that can include your uterus.
Uterine contractions are typical during orgasm, and the bladder sits anatomically in close proximity, which means that those uterine contractions can jostle your bladder around.
Throw in the extra blood flow and engorgement present in the uterine/bladder area following an orgasm, and you have a situation where your bladder is very sensitive — and any pressure on it can feel intense.
3.) Urinary Tract Infections
UTIs are the most common culprit of this sense of post-coital bladder fullness — so you shouldn’t stop being vigilant about them, especially if you know that you’re prone to them.
Seventy-five percent of UTIs are related to sexual intercourse, so it pays to be aware of your post-coital bladder tingles, even if they turn out to be nothing.
Intercourse can irritate your bladder (which is located on top of your uterus) and cause infection.
Pee after sex to get rid of bacteria that may accumulate in your urethra.
Regularly urinating after intercourse is a great preventative measure against UTIs.
If you feel a phantom bladder fullness on the regular, but never seem to have a UTI, be sure to check with your doctor to make sure it’s not something else going on.
