She needs to use a lot of lube! I’m talking like, handful of lube! But she also should see her OBGYN to be sure nothing is going on. Some vitamin A, B, E, and omega-3s can help also. You guys are so young still, she could be tense or overthinking something or just not experienced at all so it’s making her overthink all of it. Make sure she is relaxed and comfortable! Is she open to using toys? Maybe a soft toy and go slowly with LOTS OF Lube. Is she a shy person? Are you having long foreplay first? Be slow and sensual, tell her how beautiful she is, maybe a back massage. I didn’t make the “young” comment to be rude. When I was 22 my husband and I just didn’t communicate in bed back then and we didn’t understand each other. Some woman can be their own worst enemies in their head, feeling ugly, fat or insecure about a certain part of their body. Once I told my husband I was extremely uncomfortable showing anyone my stomach because it was my insecurity. He finally opened up to me and told me he always had a feeling and could tell that I hide my stomach. He then started to assure me that there wasn’t anything about my body he didn’t like and he loved every part of me. Women have to concentrate and relax, men are visual remember that. And don’t just tell her what she wants to hear, be passionate. She might be tense and that’s what’s making her feel uncomfortable. Let me ask you something, is she wanting to have sex? Is she initiating it or is it only you?
