<human>: Can you provide a brief rundown of the text in within 3 sentences?

Throwaway here, also wall of text incoming. 

So... at my work a very cute guy comes in on occasion and my coworker finally told me since I was so oblivious to it that he was flirting with me. So the last few times I've flirted with him and shown an interest and he seems to have reciprocated. Except now when I flirt with him he's acted a little shy/caught off guard and I wonder if I'm catching him off guard? He still smiles a bunch and talks to me, we share a lot of interests it seems. Camping, outdoor activities, ocean sports, etc.

He's asked me to come to his friends comedy show tonight, problem is he's older and I'm OK with that but I'm inexperienced and have only had one semi serious relationship and after my mother got cancer and I took care of her and my sister I wasn't mentally ready to think of a relationship for two years. Now I've lost weight and feel confident and happy, and suddenly guys are talking to me which I'm not used to at all.
 
Should I say "Hey want to hang out sometime?" "You seem cool, I'd really like to get to know you more?" He's trying to get into surfing and I boogie board and I said right as he was leaving "If you ever need someone to go out on the ocean with I'm game" and he said "yeah definitely!" and then he left and he didn't give me his number! 

I think I need to just make the move but I'm not sure how, also I have been overcoming social anxiety so I've been worrying about this more then I should. But he makes me so nervous because he's gorgeous and I'm not used to this kind of attention after closing myself off from the idea of a relationship for years and learning to love myself. Sorry, I just have no idea!
<bot>: I'm shy as fuck and hot older guy has flirted with me and I flirted back, now I want to initiate more time with him.
