Is it normal for a 20 year old person to date a 30 year old?

He used to play with me and watch me as a baby then he came back into my life at 14 and we start talking and he would kiss me on my cheeks and hug me tight and hold my bra strap but I noticed he doesn’t want to do the deed. Which makes me upset of course. Even when I send him sexy pictures he gets mad I get I’m a minor and all back then but now even now he doesn’t want to get too close. I’m not a minor anymore and I love him but I don’t know how he views me it’s so hard to read him please help
