<human>: Provide a brief overview of the text.

My boyfriend 'John' and I have been together for just under a year, it's serious in the sense that we are exclusive but our relationship by nature is fairly relaxed (probably because of our age).

John and I were hanging out a couple of weekends ago as his parents were away on holiday. I didn't stay over but very late and we ended up 'going further'.

I didn't take offense with him telling his friends, I did the same with my close girlfriends and I would expect him to. However, his friends' response is embarrassing and uncomfortable for me; they crowbar it into conversation as often as possible, they imitate the gesture of the act and I've been given a ridiculous nickname due to my unfortunate love of oreos - 'double-stuff'.

John and his friends have a relaxed and easy going vibe and any sort of serious talk gets shouted down and he gets accused of 'taking the moral high ground'. He has tried to talk to them but he's a bit overwhelmed and I can understand why, there's a sort of 'herd mentality' where its very difficult for anyone to see reason.

I get extremely embarrassed by any sort of overtly sexual discussion due to my Christian upbringing and its making me awkward socially and reluctant to go out with John and have fun, which is really unfortunate as I normally enjoy hanging out with him and his friends, they're nice boys but as I have said extremely immature. I really don't know what to do, I feel socially crippled by this.
<bot>: Went further with my boyfriend, his friends are being extremely immature about it which has escalated to the point that i feel extremely uncomfortable around them in a social setting, not sure what to do about this.
