It's difficult to answer this question. Mainly by being intimate, it may lead to something, but you really need to respect and pay attention to her comfort level.
You should talk to her about where her comfort level is before you attempt anything. This is to show you respect her and will actually strengthen your relationship.
It is OK for you to feel like your girlfriend doesn't trust you. You are entitled to your own feelings and if that is what you feel,that is fine. However, you should discuss your feelings with your girlfriend if they are making you feel bad.
You feel closer to your girlfriend after sex because you went inside her and have become one.
Have you?
my girlfriend feel tired and sick
After cheating on their girlfriend, guys may feel guilty, ashamed, and regretful for their actions. They may also feel anxious about the consequences of their behavior and fear losing their partner's trust.
dunno touch her
Answer You don't. You just don't. And I really feel sorry for your girlfriend.
Tell her/him how you feel about them.
This makes no sense either.
How do you feel? Exactly!
When your girlfriend says she does feel like you are dating, you need to ask her why. When you find out the reason, you need to try and repair the relationship.
Gently explain the situation to your girlfriend. A mix of jealousy and worry can be put at easy if you trust your girlfriend to be loyal. Tell her that you do not feel comfortable with it, but let her know that you trust her.
