<human>: So I've recently been going clubbing and going to pubs again and on a few occasions I have gone back to a girls house or they have come back to mine for a night of fun. The nights are pretty normal, just sex and making out really. But since I was previously in a LTR, I've kind of fallen in love with eating a girl out and just purely pleasuring them. The problem is, I don't want to/feel comfortable going down if I don't know if they are infection-free or overall "clean" down there. Whats someone I can ask or find out that wouldn't be considered rude?

Provide a brief overview of the text.
<bot>: I want to give girls I hook up with oral, how can I be sure they are infection-free/"clean"?
