The first time I ever took shrooms I was 14 and didn't know anything about them or psychedelics in general, nothing, my dealer just didn't mention it and I just figured they were like weed but stronger, dumb but I was young and had no internet back then.
I ate about 3 gr before they really kicked in, and it wasn't a very good experience to say the least.
But now you can inform yourself very well, and personally I think you can handle a mild trip just perfectly on your own.
I agree with what's said before, just start low and increase accordingly, if you can get benzos that would be great to have with you as well for when things get too difficult.
When you're a very positive person filled with energy and don't overanalyze things too much you can most likely handle a stronger trip as well, but just start low and you're good to go.
