the feeling i get when i see her

Ok so I have an amazing gf and I love her with all my heart.
She's the most important person in my life and I'm glad I have her to love.
So whenever I'm with her or whenever she touches me (no dirty thoughts) I get this weird feeling on my stomach bit its a good feeling.
Is it a good thing or a bad thing? What does it mean? Uuug I'm so clueless. Plz help.
