I've Had a Hard Time Being Affectionate in a Relationship

I've really had a hard time with being affectionate in a relationship. It just not come naturally to me for whatever reason. And so you can imagine, as a freshman in high school with my first potential boy friend, kind of, this was very uncomfortable for me. So basically, i don't remember how we even started kind dating,. But i remember he sent a text to me, and he was basily like, m i ave a crush on you. Like, i really like you, baboi. And then from that point on, we were kind of dating, but we didn't really ever hang out alone. it was like, very much not a real relationship.
