So me and my boyfriend don’t have sex too often because I’m afraid of the pain that follows after. His dick is pretty thick so it stretches and tears my vagina a little. After sex I get this stinging sensation around the hole of my vagina and it almost feels like my crotch is on fire, this “fire crotch” feeling lasts shorter but the stinging stays and is really bad when I urinate. I’m wondering if it’s because the only time my vagina gets stretched is when I have sex because I don’t masturbate on my own. It also gets dry right when I cum when I thought it should get more wet. So essentially I’m wondering will it help if I start masturbating every day to keep it stretched? And should I maybe take a medication to help with natural lubrication? I really enjoy having sex with my boyfriend and I want to have it more often but the fear of having that pain after stops me.
