Sexy scenes being a turn on

Alrighty loves. I am about halfway through writing my first book. It is slightly erotic but mostly in just romance. While erotica is one of the main genres I read I have never had this happen like this.

When I read erotica it is almost like watching porn for me. I get all sorts of hot and bothered.

I was writing a sex scene for my book and literally had to change my panties and had to calm myself down before I could continue writing.

Is this weird? Has anything similar happened to anyone else?
