How can me an my boyfriend spice up the sex?

We’re hitting the 6 month mark and are getting more & more comfortable sexually. Last time I stayed at his he brought a vibrator into the bedroom, and discovered I liked having my hair pulled and being choked. He’ll also call me his ‘little slut’ and a ‘good girl’ and I’m ngl it gets me sooooo fucking wet💦 like we do have bomb ass sex, but I’m quite shy sexually (for complex reasons) so he’ll ask me to get off with the vibrator and as much as I want to I can’t bring myself to do it, or he’ll tell me to beg for it deeper or say how much I want it, and I’m so so into the dominance but I’m so shy. Anyone know how I can basically get my sexual confidence up because I do think it’d be better for us both.

And again back to the first question about spicing it up, I am majorly into dominance so does anyone have any suggestions????

Please no hate aswelllll
