Intimacy issues - advice plz

Im talking to a guy know who i’ve been working with and getting to know for a little over two months now.

We have had lots of flirtatious moments and ive even seen him get nervous around me (sitting up straight or fixing his hair right as i walk over to him) We even text each other through the day even though we are working!

Anyway we got into a semi serious conversation the other day and i could tell he was indirectly saying that he liked “someone” but was afraid of hurting them because he gets really clingy in relationships. He said he pushed an ex away by doing this. i guess hes afraid of being overbearing with me.

I told him he just has to make sure the person feels the same way about him and it will be okay. He makes me really happy, but i dont know exactly how to express this.

Update:

i can tell he is really shying away from acting intimate with me( getting close to kiss or conversations indirectly about sex) . He gets really nervous. I also notice that he gets aroused sometimes we we play around flirt but if i try to openly kiss him or something he gets nervous. He said he is still a virgin, but im not trying to have sex with him or even really kiss him, id just like for things to mutually go to the next level or romance, you know?

Btw im 21 and he is 19
