Hello, I'm a nineteen year old lesbian in a committed and loving relationship with another woman! I have been in multiple relationships before her and I've always made my partner stop when I start to feel the buildup of an orgasm. It feels really nice, and I love my current girlfriend so much and want to get there with her. But it's like there's a wall there and I always make her stop even though it feels incredible. I don't know if I'm afraid or what, but I trust her completely and I know this with all my heart. Thoughts are appreciated!
