18 and 26 age gap

Hi guys. I turned 18 in October and I am on a trip so I decided to download grindr because I’d never given oral before and I wanted to try it out. This guy that was 26 chatted me and we exchanged pictures of ourselves and he asked if I wanted to meetup for oral and I agreed. He was really nice and before we did anything he insisted we just cuddle together and talk, where I told him I was an incoming math major and he asked if I was 18 then which I said yes to which surprised him a little (I was confused cus my profile said I was 18) then we did everything and he was really nice and patient through out the entire thing and it was an enjoyable experience I just don’t have the energy to do that again I feel like it’s something I’d be in the mood for like twice a year lol.

Anyways he chatted me yesterday and asked if I wanted to meet up with him again and I told him the truth that I didn’t want to because bjs take a lot more energy than I thought and he said we can just walk around the city instead. I told my friends about the experience and the opinions are mixed some people think I should but some ppl think I shouldn’t due to the age gap, which I do think is weird but then again he seemed like a normal person. I was just wondering if I could get any extra opinions on the matter because I’m on the fence on whether I should or should not meet up with him. Honestly I agreed to meet up at the time because I was horny but now that I’m more clearer I do think the age gap is odd to me but like I said he didn’t seem weird and it wasn’t a bad experience either. Maybe I am being overly cautious but I am just worried in case. Pls help!!

TLDR; I met up with a guy that’s 26 for oral sex and he wants to meet up again casually, but my friends think the age gap is weird and I can see where they’re coming from, but he seems normal
