Advice.... please....more confident guy

So the guy I'm dating showed me a more confident side of him today while we were making out.... he pulled me closer and closer to him with each kiss.... and pulled my lips to his neck...

He's not normally the type to make out if someone is around l... and my sister was on the deck at the time...

So here is what I need advice on... please no hate about him being childish...

He had his hand down my denim shorts/panties .... and was rubbing me... for a little bit... he pulled his hand out because he was afraid he heard my sister coming near the door...

He said his fingers smell like fish because of it 🤔 And in the middle of kissing me said "make sure you clean yourself a little better for me"

I know we all have our different smells and it's natural... my period is supposed to come in a few days so I'm wondering if that could be a reason.... but I'm having a hard time figuring out how to explain it to him

Without feeling upset that he might not want to touch me like that again 🤔

I know I'm over thinking this a little because that's what my anxiety does.... it takes over me. 😔

Any advice would be great 👍 and appreciated 🙂
