It's important to be sensitive and talk openly about things that are personal and related to relationships. It's important to be open and honest with your girlfriend about sexual behavior if she doesn't like it or feels fine with it. A good friendship depends on both people knowing what the other person wants, needs, and limits are.
Here are some ideas for how to deal with this problem:
Talk to your girlfriend about how you feel and what worries you. It's important to say what you want to say in a way that doesn't judge or hurt others. Make sure she has a safe place to talk about how she feels as well. Allow your girlfriend to talk about how she feels about being close to you. Learn about her thoughts, feelings, and any issues that are making her uncomfortable. Active listening is a key part of communicating well.
If the problem keeps coming up and is hard for both of you to deal with on your own, you might want to talk to a relationship counselor or therapist. A professional can give you advice and help you and your partner figure out what's really going on. Keep in mind that everyone has different needs and levels of comfort when it comes to closeness. Couples need to work together to find things you both like about each other and build a relationship that works for both of you. If the problem keeps happening, getting help from a professional can help you figure out and fix the real problems.
