<human>: Condense the text into a few key points

I've been seeing this guy for a little over a month. He's never had success in the dating department, so I've been his first for everything. First kiss, first make out, etc. The other night he mentioned off handedly how he's never had a hickey, and I thought, 'eh, a little high school, but what the hell.' 

He has a very close circle of friends(mostly 18F) that are really cliqueish. They seemed a little standoffish towards me, but I've only met them twice, briefly.

 I placed the hickey too high up, and his shirt just barely didn't cover it, and it slightly covered when he wore a hoodie. Either way, he ended up telling his best friends and they're the high strung Christian type, so they immediately asked him if it went any further(as in, sexually than just hickeys),it didn't and he told them that, and they replied with good, and if it did they'd kill me. 

I already got the gist that they didn't like me, but now they probably think I'm some harlot. I might be seeing them tomorrow night. What the hell do I say or do?
<bot>: BFs friends probably think I'm some she-devil after hickey mishap, I don't know what to say, or if I should confront them at all.
