Hi Welcome to HCM
I understand your concern. However, the information you have provided is very limited to offer any advice. Looks like the frequent stooling which I assume means diarrhea could be due to food poisoning
or upset stomach.
The unprotected sex as you have mentioned may be related to back pain
, although I would advice consulting your primary physician to rule out any possibility of urinary tract infection
. Other symptoms such as migraine
is unlikely to be related to the sex.
Hope this helps.
