Hey Hellen. I’m sorry you experienced pain. The first time I attempted penetrative sex, I felt the same pain. And honestly it could be because you were tight, your hymen could be too big and unable to tear without a doctor intervention, or vaginismus. It could many things. I never shoot down an opportunity to make an app with the doctor. It is always better to be safe than sorry. But you could first try dilation? There are kits out there that range from pinky sized to an average penis size and you can even buy larger sizes. The idea is to be able to insert a dilator bigger than your partner so his penis will always go in with ease and your vagina will accommodate it easily! And pain free! It really could be that you were nervous, your muscles were tight, you weren’t aroused enough due to nerves. But maybe you can buy a couple different sized toys? Play with those first before sex so your vagina can have a warm up with penetration. Start small and work your way up to larger sizes but never push yourself! We don’t want to cause pain we want to solve it! 🙂 So maybe start there. Try some insertable toys smaller than a penis and see how you do with that. If pain persists, and your gut is telling you something isn’t right, absolutely see a doctor! There is also A LOT of incredible info in this forum!
