pumping stuff in the uk?

hey! so im very new at this and have absolutely no idea what im doing 😭 but i really need help. i’ve been getting increasingly dysphoric about not having big enough bottom growth (been on t for 5 years, yikes) to penetrate my partner and i have absolutely no idea what pumping stuff to get here in the UK for a decent price. if anyone has any suggestions please let me know! all suggestions are appreciated ❤️
