I need some advice.

so today my boyfriend (he’s 17) and me (14) saw each other, which doesn’t happen too often due to him living in a different part of london, i’m on my period at the moment and today he was horny, more than usual anyways, and i have always been very shy and not let guys or anyone touch me really apart from him, he was my first kiss, first hug even 😂 and today he was super horny and when we went back to mine he wanted head and i didn’t know what to do, i’d never given head before and i was really scared i was gonna do something wrong and my mum was upstairs and i didn’t need her finding out. but anyways it happened and i gave him head but i feel like i was so bad at it :( i don’t know if i was ready or not (he wasn’t really pressuring me i could’ve said no but i thought i was ready) could anyone give me some tips or advice cause i kinda need it rn 🖤
