So you are co-virginity acceptors, she is younger than you, and you will have sweaty balls?
I would recommend shaking up a bottle of 7up pre-cock ingestion and giving yourself a bit of a refresher spray. Not only will the bubbles cleanse you, but the lemon-lime scent will attract her deeper into your man parts, enforcing the deep, soulful connection you have before you drop your load on her. By load, I mean ejaculate. Do not poop on your lover. Unless she tries to run.
