15yr old ds and girls

[Dooohhh]

My 15yr old ds has an app on his iPad which basically is texting for free.
He has never said anything to me about girls and girls haven't really been part of his friendship groups.
On Sunday he wants to go out with his mates from his (boys) school. I am normally fine with this.
He has started talking about a girl who goes on the tube at the same time as him in the pm. I was worried about him (not because of this) and so I had a look on his iPad. He was talking to several girls who it turns out he is going out with on Sunday. His texts seemed quite unlike him, and when a girl said she couldn't come he said it wouldnt be the same without her because there wouldn't be the same ammount of girls as boys (??). The girl is now coming but I am now worried what they will get up to.
I have to go up to the NEC (from London) so I am not really sure what to do??
Any advice appreciated!

I dont understand what you are asking?

He is 15! of course he is wanting to spend time with girls.

What are you worried he is going to get up to?

Well firstly he has always snook alchahol back to his room and he looks about 18 and would easily be served, and secondly I have a feeling they might all be having sex.
Am I just being over protective??

If you think he is having sex then you need to buy him some condoms and make sure he is protecting himself. If he is then you wont be able to stop him but you can make sure he is protected.

I can't imagine they are all going to go out and have group sex on Sunday? But if you think he is likely to, Angel is entirely right.
I can't imagine why you are surprised that he speaks differently to teenage girls from how he speaks to you?!

How are you going to stop him having sex if he is planning that? Will he listen to you if you tell him not to or are you going to lock him in his room for the foreseeable future?

I only have younger children but I doubt an orgy is in the offing!

Undo those apron strings .. He is 15 give him some trust

I agree, but he will never let anyone on his iPad, and he would flip if he knew I had been on it.
Also, I'm just not sure I can trust him to go out now, but if I don't let him go, we will loose our trust together
Should I let him go??

Are you for real ?

I have never really been able to trust him, and last time he went out with his friends he came back at 11 hammered.
I just don't want anything to go wrong as I am not there, and can't get to him if he needs me

Does he know about safe sex?
Does he actually know about the facts of live, not the drivvel they teach in schools?
Have you spoke to him about the effects of alcohol?
Does he know that he doesn't have to get drunk/stoned/laid because his mates are doing it?
Did you find out why he got hammered.. Was it not knowing limits, going along with things or what?

But, fwiw, genders can mix fine without it always turning into an orgy. Not all teens go out and get hammered, and usually its because going along with the group, not knowing the limits, or to piss off controlling overbearing parents.

Yes, I have talked to him about all of that as well as his 'going out rules'.
Sadly, he is the ring leader, as his friends look a lot younger, he is always the one that gets things started and makes things happen
