Help me please😅

So my boyfriend of 2 an half years asked if we could take our relationship further sex wise. I said yes! I feel really comfortable with him an everything. I gave him a blowjob an he liked to kill me cause when he finished his eyes were rolled in the back of his head an he was breathing heavy. An then 5 minutes later his brother walked in the house so we didn’t have time for anything else.

He told he was gonna get me back next time.

But I’m worried like I’ll smell or that he’ll think I taste weird or something. An it’s worrying me.

What can I do to make sure I don’t smell or taste weird😅😬
