I (26m) while having sex with my girlfriend (23f) sometimes want to switch from having intercourse to going down on her for a while. Usually i feel like doing it when i want to give my penis a break or sometimes if we have been fucking for more than 10-15 minutes straight i go a bit soft and it takes a few minutes for me to get hard again. During this time i would like to go down on her as i dont want to keep things going and keep her and myself aroused. But she wont let me do it. I ask her why and she says "oral is just for foreplay". I understand that she enjoys penetrative sex probably even more than oral (rare for women as far as i know), but i feel like me going down on her when my penis isnt fully erect anymore is a better alternative than stopping everything and just waiting for me to get hard again. That just kills the mood.

Does anyone else have experience with their female partner only allowing to go down on her during "foreplay" and not going back and forth between oral and intercourse? The problem is that if i lose my erection before i cum and i dont go down on her while i wait for the erection to come back she wont be wet anymore and that makes intercourse trickier (oh and btw shes also not a fan of using lube). Not sure what to do here and what some potential solutions are
