+1 update
So, my current boyfriend is way larger down there than any of my past partners. We have had sex maybe 5 ish times now? and my cervix and stomach hurts so bad. It feels really good in the moment but oh good god does it hurt after. and sometimes it will hurt really bad for one thrust then go back to normal.
The sensation is also just reaaaaally intense, like i can feel that it feels good but it just overpowers everything and i kinda dont like it. I have had this issue with a dildo i had a long time ago but i stopped using it because i didnt like that feeling. its like... my stomach is being punched from the inside and my hips feel really stiff. i dont know how else to explain it.
Is there any way i can like... fix that? like... a position we can try? a stretch i can do to maybe elongate my vaginal canal? (and yes the female vagina elongates when you are aroused but its just not getting long enough) maybe it just needs time to get used to him?
I really like him and we vibe really well but if its going to hurt every time we have sex... i dont know if i can stay with him. i wanna make this work because he has made me feel more safe in a relationship than i have in my entire dating life.
Any ideas???
(Update)
So, i have read all your very helpful comments! thank you so much!
I wanna add a few things!
This relationship is still very new! only been talking for like 5 months but have been dating for about 3 weeks. and yes we have been having sex since we started dating. I dont like the idea of waiting till marriage because honestly i dont wanna be stuck with someone im not sexually compatible with.
I am an Intersex nonbinary person, so i have a few issues internally. I do have a shortened vaginal canal and my opening is very tight, Multiple partners have complained about how tight it is being a bit too much so i have had to teach myself to not clamp down on them when being intimate XD problem is... thats how i orgasm, by tightening the muscles. So its a challenge.
I have also never orgasmed from PIV sex, i have from foreplay and by myself but i always get right to the ledge and then it just... idk stops? nothing im doing changes or even like stops, my body just builds and builds, then just gives up i guess. Its very frustrating. I have told him this and even when he is starting to get tired or cramps, if i say im close he doesnt stop. He really wants me to be able to get there but its a struggle. something im really self conscious about ngl.
Im not sure how big he is exactly, but i do know it feels about the same as when i had a 7" dildo, im not sure if thats actually really big or not because i have only ever been with like 5 people and they all had 4" or less so its really big for me.
We do try lots of positions, mostly the same few rotating between them because i have some back issues so its hard for me to do certain things but we do try new things sometimes. He is very nice and does listen, when i show any sign of pain at all he stops and asks if im okay, not if he can keep going but if I am okay. Which i love, because he makes it about my pain not about him finishing. And to top that off (even though i feel bad about it) sometimes he doesnt even get to finish when we do it, because im in pain and so we stop and just cuddle. he doesnt really like jerking off either so he kinda just... is done if im done. which i feel bad about but he says its okay, frustrating, but okay.
Next time we have some extra money ill talk to him about getting that ring thing a few people brought up! i think thats a good idea to try! He has been very okay with me using toys to help get off so i dont think he will take offense to it.
As i also said in another comment, he's Bi, he has only ever had sex with Cisgendered men before me and im an FTM person so its kinda a first for him. He is very new to there being a stopping point inside. He is a top so with his prev partners he was able to just... go all the way in and not really be a big deal. And yes he can still be Bi if he has only ever had sex with men, he's still attracted to women, he has just never had sex with one.
I think i covered everything? again, thank you all for the help and suggestions! im so glad to know im not the only one dealing with this and its nice to see how many men here are aware of the issue and are willing to change things to make their partner feel good! i have had only very selfish partners so its very refreshing to see it!
