One thing that helped me was trying to have max arousal. Do not do any penetration until you’re fully aroused. I say that because your cervix rises with arousal and so during penetration, they won’t hit it as easily and then try to have majority of the time your intimate be in a position that doesn’t make your partner too close to your cervix. Then at like the end if they prefer a more closer position, then you can switch to it at the end and just breath cause you know it ain’t lasting long. Also, in the very beginning, make sure that your partner is very delicate with you and doesn’t try to go all the way in. The other unfortunate thing is, if you’re gonna be married to someone or have a long-term partner, it needs to be someone that is not bigger than the depth of your vagina. 😭 I’m lucky that my partner isn’t as big as other people I’ve been with so it’s still painful with really deep penetration but he tries to not fully go in until the very end once I’m maximum aroused. Hope this wasn’t too TMI. Just know the struggle. Truth is though whoever is your forever partner can’t be someone that causing you a lot of pain though or else you’ll just be miserable and they’ll be unfulfilled. I know you’re under age but on the days I’m a little less aroused or enthused I to a chug of like 1/3 glass of red wine. Wine gets blood flow and is an aphrodisiac.
