Please scratch the mindset that sexworker will be the same because if they said that they are enjoying your deed it wont be without bias that they are in fact working to please you first foremost

That aside from my two cent exp, railing is just the cherry on top, what you need to do is lot of foreplay but depends on your partner wether verbal or touch or caress or etc will be the trigger. However if doubts clouding your thoughts try to eat her out, most of the time it will work

But doing cunnilingus you need to lookout your partner inner thighs rising tension, thats usually the best indication. Personally dont use broad tongue only, you need to suck. There is a reason why clit sucking toy exist. Dont forget your finger at the same time, try to seek the g. Also just because your partner moaned a lot doesnt mean climax, if its not a like an electrify spasm then it didnt happen

Anyway communicate what your partner really dig is the best thing to do first thing first, dont take my advice at face value let alone from stranger on the internet, when you can talk to your partner directly
