i have a quick question about taking my temperature because i am not feeling good?

i took my temperature earlier today because because i stayed home from work because i was sick. i went to find the oral thermomter but then i went to use it i found out that it was dead. and unfortunately the only thermometer i found that worked was a rectal thermometer, so much to my dismay i took my temp rectally and my temp was 99.1. i mean i didn't want to take my temperature rectally at all but the oral thermometer was broken and the rectal thermometer was all i had. yeah i took my temp rectally and i hated it so bad, the whole 5 minutes it was in me i was thinking is time up yet. it was a horrible experience for me, it is not something that i want every time i am sick i can tell u that much. i just wanted to get it over with. i am going to take my temp again 2night before bedtime, i after what happened earlier today i DO NOT AT ALL WISH TO TAKE MY TEMP RECTALLY.

so i was wondering if i took the rectal thermometer and cleaned it very good, can i use it under my arm? if i can clean it off and use it under my arm great and if not then i will have to take it rectally again do to my dismay, until i can go and get an oral thermometer.
