When do I bring up getting more ual for the first time with girlfriend?

Next time you guys are making out, be a little bit more sensual with her. Put your hand on her knee and gradually become more and more touchy. I think five weeks is definitely a good time to go to the next step, even if it is just feeling up or . If she shys away from your hands on her or acts uncomfortable stop. Or just politely say before or after hooking up, "I really need to talk to you about going to the next level." Explain it the exact same way you did above (you just want to explore, want to show you can care for her, don't truly need it, etc.) You'll feel very relieved once you talk about it, and chances are she wants to speak with you about it too! Hope all goes well.
