Fingering

So I tried fingering my self for the first time tonight, I could only get my finger like halfway in before it felt like I couldn’t go any further, it was like I hit another layer of skin, nothing has ever been in there before so is that my hymen? And if so how do I get past it without it being super uncomfortable, because it didn’t feel good and I was super lubed up so it wasn’t that, it just wasn’t pleasurable at all
