I 31F have been with my 32M SO for 12 years. We met in high school and he’s the only guy I’ve ever been with. We have great s3x, but we are stuck in a frustrating loop where he finishes within a minute of having s3x and then I can never finish because he gets tired or wants to be done since he already finished and doesn’t have it in him. Foreplay helps both of us, but to the point that he’s getting too ramped up I think? How can we fix this?
