Please help.

So I love my boyfriend so much but I kinda feel bad because I know he wants to farther with me, but I'm being kind of stand-offish and I feel like I'm giving him mixed signals. He's super respectful and isn't pressuring me in any way, and I really do want to go farther with him! I'm just so self conscious of my body! The other day he was feeling my boobs outside my shirt and I kinda enjoyed it but I was so embarrassed because I'm so small:( He let me put my hands inside his shirt but then he slowly started reaching under my shirt for my boobs but I wouldn't let him because I was probably really nervous sweaty and I feel like I'm just not attractive in general. My boobs are also really hairy but its like more than I could pluck:/ I feel so awful because he felt so guilty but I know its mostly my fault. I totally wouldn't of minded it if I just had a better bod! I'm 19 and I feel like I need to get over it so I can eventually have sexual relationships, but right now I'm just so awkward ugh any advice would be great
