Whoa whoa whoa, slow down there buddy!
First of all, you bought the wrong lube. You needed the rectal lube, return the one you have. Promise the old lady at the register that's its unused. Wink at her, she'll understand.
Next, and last, why latex gloves? That poor man could have a latex allergy and then what? No fun, no games, just a bad rash and a worse story. Always go with neoprene gloves man, always.
Lastly, how big is the box of condoms? Family pack at least? Latex-free for sure?
Use good judgment, preemptively lubing your johnson is a wonderful start.
We want pics.
