Sex help/ question

To start off I’m 24 and I’m still wondering what it’s like to finish. 😭 I’ve had a few partners and I’ve tried experimenting with myself and got myself a dildo too BUT I couldn’t seem to get myself to finish. I would always get close to finishing but for some reason I couldn’t get there with myself or a partner. Not too long ago I think I did finish with a guy but I wasn’t sure and I guess if I had to ask myself if I did finish then maybe I don’t think I did? I also started dating this guy and we had great sex that he even made me squirt (I’ve never squirted before either). Squirting felt great and he was able to make me squirt a few times back to back. Now I read a few posts on here saying that squirting is not the same thing as finishing so how can I get myself to finish? Is squiring not the same as finishing? Help please 😩😭😭
