VaginaPagina

Hi everyone, it's me again! 

So this is an issue that I've had on and off for a while, and now that I have some extra free time I thought I would try and be a little more proactive about it. 

The V where my outer labia meet at the "bottom" of my vagina opening (so the end close to the butt lol) gets super stretched out, even torn a bit during sex sometimes. There are just some position that hurt it more than others (missionary, playing with toys at a certain angle). Even if it doesn't hurt right away it gets irritated and sore fairly quickly, which really sucks. Is there anything I can do about it? I'm fairly close to just seeing if I can get it surgically cut. I feel like I just need a millimeter or two more of space, and then everything will be better (granted, I don't really want surgery, and my insurance would probably not cover it, so it's a fantasy for now). 

Any ideas? Any way to make it less sensitive/painful? 

Thanks so much! 

Edit: I should add that lubrication is not a problem. I've used coconut oil, silicone based lube, and water-based lube, and we generally don't use condoms.
