taking her temperature
Euphemism for having sexual relations with an incredibly attractive woman, i.e. you're "taking her temperature" vaginally with your penis instead of a thermometer.
Example:
The gorgeous blonde paralegal with whom you work walks into your office, and your first thought is "I SO want to lick her pussy and take her temperature."
