My first dildo.. TMI?

21F I’m a virgin, I tried having sex with my boyfriend for the first time this year and well we just couldn’t it was too tight and painful to just try to stick it in. Anyways I recently got a small dildo to stretch myself a little and try using it, it hurts at first but I can get it in.

But when I use it, it’s kinda not the amazing feeling you’d expect? It feels like I have to pee right then and there, is that normal? How is it supposed to feel? This is very new to me, I’m not sure what I’m doing or how this is supposed to feel.
