Ex vs current boyfriend 😬

Rumor has it that white dicks are smaller than black dicks... My ex had to be have about a 5.5-6" dick. He was 19... a GROWN MAN. (Black ) My current bf has a little more than a 7.5" pushing 8". He is 16! (White) Lets just say in my case that stereotype isn't true😏 Idk If I can handle my current bf 😩 I haven't had sex in 6 months! Any tips on how to make our first time together pleasurable for me?
