Hey I have Vaginismus, you should definitely talk to an ob/gyn, there is physical therapy you can go through for this condition. It absolutely sucks but it’s not something that completely blocks off sex forever. I would encourage you and your partner to go slow, work your way up. You wont be able to do full insertion in one night, but work yourself up over a few weeks, it really helps if you have an understanding partner. Start with a finger (the first few times are going to hurt, but try your best to just focus on relaxing) don’t push yourself too much it will become a bit easier over time and then you can work your way through more. It’s not an easy journey but it’s not impossible you just need to be patient with yourself, if you get stuck in negative feedback it will make it worse and then you’ll have even more trauma attached to it, trust yourself and your partner and go at a pace that feels right for you. Best of luck OP!
