If you have heard of
bad girls bible (the website), then this may be a helpful resource for position-naming, though there are plenty of duplicates!
note: The depictions there are artistic watercolour-styled and not graphic but still not sfw in most cases. For me personally:
- Viennese Oyster Position https://i.ibb.co/5967tD2/VOP.png
- Launch pad https://i.ibb.co/vBQBHNG/LPP.png
- Leapfrog https://i.ibb.co/M8HNdSh/LFP.png
- Ballerina (needs a fair bit of prep and preexisting flexibility) https://i.ibb.co/7nV0BtK/BP.png
- Triceratops https://i.ibb.co/Y31YgX2/TP.png
- Stand and carry https://i.ibb.co/5YzdxdW/SCP.png
A lot of my favourites would i guess be classified as positions where my partner would have a lot of control. I enjoy that feeling as well as my boundaries tested. They all (except ballerina) can be adjusted quite easily to open me up more or close me down a bit more, depending on the guy.
The only time in general i enjoy the opposite dynamic is for cowgirl especially if the guy is large(r) than average, i am sure this is well understood so this is probably most safe and clean level of detail i should go into.
