There are a few topics on oral including this one but ultimately everyone is different. My partner is complicated, sometimes she likes gentle clit teasing and other times she likes rough. Likewise some days butt play combined with oral can give her very powerful orgasms and other days teasing her butt will dull her mood. I’d suggest you read this post and others but ultimately listen to her feedback and tells, moans or movements, experiment adding toys and combined play, butt, vagina breasts or any other body part she enjoys being touched.
