so I finally met mr right BUT

I'm a shallow fool. I've known this guy for several months and we met through a friend, we've been hanging out a lot lately due to having mutual friends. He's everything I want on paper - tall, rich, super funny, a good listener, great kisser, handsome. We went on one date and it was bloody perfect. I left wanting to see him more. He's asked me to meet him for another date this week but I feel like this is where my evil side comes in. I would like to point out that he is 1.5 years younger. I've never dated a younger guy before but I've come to learn that age is just a number. I'll like to add that he is super mature, has a stable job.Now, the real problem lies with how young he looks. Not only is he younger but he looks about 3-4 years younger(we're both in mid 20's). My friend was quick to judge a picture of us, she said "girl he's cute but he looks super young". He has a baby face but his stubble defo helps. I look about 1-2 years younger(more without make up), I feel like when I am going to meet him, I have to wear as little make up as possible so we look slightly the same age.He's an awesome guy however. I was at a party and someone got hurt and he was quick to bandage her up etc and it made me feel like I was a horrible human to doubt him because he looks slighty young. I have no idea what to say to him before our second date comes. I'll be attending a good friends party soon and I know he'll be there so its not like I can just brush this off. What do I do? Very confused? I feel like he deserves better than me!

* i would also like to add I am a people pleaser if I wasnt I would have probably been on a date with him right now*
