My girlfriend (23f) and I (26M) use condoms as our birth control method. She doesn't like condoms as she says they lead to her getting dry but since shes not on any birth control and im not comfortable with the pull out method we are stuck using condoms (which i do not mind). However after about 4-5 minutes of intercourse things get pretty dry and if i pull out i can feel the condom is bone dry. My first thought for a solution was just using lube so i bought both water based and silicone based to try but my girlfriend is not a fan of lubes and prefers things to be "natural".

We do lots of foreplay before intercourse and she is very lubricated in the first few minutes of intercourse, the problems start after that. I can see that things get uncomfortable for her and a couple times she even asked me to stop which we did of course. Not really sure what to do here because now i feel like if i do not cum in the first 4-5 minutes of intercourse im just making her uncomfortable and i dont want to do that.

Anybody faced this issue before? Do you have any suggestions for solutions?
