Guys, I banged this tinder girl a few times. From the second date I was not putting a condom as she told me she's on a pill. However I still never finish inside her but on her face/mouth. But now I realized that I can't trust a person from tinder that I met a few times about such important thing.

So here's my question - how do I revert back to using condoms with her without it being akward? Any joke I can make? Or should I be honest and say I don't feel fully comfortable without it yet?
