He bought warming gel?

So yesterday my boyfriend and I went to buy condoms, he left me in the car. He went in and he took awhile, he doesn't live here so he's not very familiar with the store, he lives about 45 minutes away. So, my mom was at lunch so we decided to go out to the bad lands and have sex, when we get there and get settle he opens the box, the bottom of it said 20. He finds this little bottle, (picture of it below) and instructions with it. I read the box and it's a ladies warming gel, to get a better orgasm. We both laugh and he's pissed cause he wasted $9 on it. So he puts some on my leg, after a couple minutes of massaging it in, my leg starts tingling. I freak out and he just laughs, so we go back to the store. I go in this time because he's embarrassed, I grab the condoms and leave. I just thought it was funny because he was so confused. The bottom of it said 20 so he was thinking, oh 20 condoms, it was so funny.
