Sorry if tmi just need help

Ny

hi ladies I wanted to know if i’m the only one who experienced this and if this abnormal, but I like to use my vibrator before sex but earlier in the day and I usually get two orgasms out. However when I have sex later at night I get nauseous to the point I am about to throw up. I regularly get check and keep my hygiene up so I know it’s not any infections.
