I'm Shy

Karis
I like this guy and he likes me. He just got out of a relationship and said he just wants "fun" not another relationship. He likes me a lot tho so I've convinced him to take it slow. The problem is that I'm extremely shy and I get so nervous around him and he just wants to jump into things so fast. He's already felt my ass and we haven't even hugged yet. He's already sending dick pics and we were just friends a few days  ago. It feels like I'm getting serious with a friend, not just someone I like. It's a weird feeling like my friend is touching my ass. How can I feel more comfortable with him? Thank you so much in advance!
