So me and my gf (yes, same sex relationship, just to avoid any confusion) live in a semi-detached house and the walls apparently are really really thin. Our last house was a semi, but the walls seemed much thicker, so we never had to worry about being quiet when we were getting intimate (when my dd was away anyway)
In this house, I can hear pretty much every conversation our neighbour is having, so there's absolutely no reason it isn't the same for her.
Now, in the thrills of passion, the last thing you want to be worrying about is keeping down the noise, but then when you have kids, you get used to it I suppose. This house has 3 floors though and my dd is on a separate floor to us, so that side of things isn't really a problem. So we should be free to just let go and be free to be fairly loud (to an extent obviously), but as I say, not with these seemingly, paper thin walls 
My dp and I have different ideas of keeping it down. Well, basically she just doesn't and I try to, because I know the neighbour must hear everything
I see her every morning when I take my dd to school, (our dc's don't go to the same school though) whereas my dp never has to see her at all, so she really doesn't feel embarrassed or uncomfortable.
Don't get me wrong, I like hearing how much my dp is enjoying it, but I really feel like I might need to say something.......again. I already did once before, but I don't think she realises how embarrassed I am. Should I be?
So what would you do? Should I ask her again? Would that be really offensive or upsetting?
I'm just getting more and more embarrassed every time I see our neighbour and sometimes during sex, I can't let go and relax, because I know that she can hear everything! I don't want it to turn into a thing iyswim, but I don't want to upset my dp either.
Advice please
