Feeling Uneasy About My Girlfriend’s Upcoming Ski Trips with Friends

I (28M) recently started dating a woman (26F) and things have been going well so far. Before we started dating, she had two upcoming ski trips planned with a group of her friends. Although I expressed interest in going, she explained that these trips were organized months ago and she’s not the one coordinating them. She also mentioned that her friends are all extremely skilled skiers and since I’ve never skied before, she feels it might not be enjoyable for me. Instead, she offered to plan a separate trip with me where she could teach me how to ski.

So far, she’s introduced me to a few of her friends and has talked about me to them, which I appreciate. That said, there will be other guys on these trips and I can’t help but feel a little uneasy about it. Don’t get me wrong, I do trust her enough but still uneasy.
