<human>: Give me a shortened version of the text

We haven't always had this problem we've been together almost 2 years now, but over the last few months I have been going very quickly during sex. In the past I would usually last an average of about 7 minutes which was great for both of us. However now it's been roughly a minute before I end up finishing. Naturally this is disappointing for her, I still get her to go, but she prefers to have it done during penetration. And for me it's extremely frustrating as I get no enjoyment finishing so quickly and I have been really beating myself up about it.

I know most people generally say longer foreplay pleasure her in other ways. I definitely do that, but we both enjoy the penetrative part the most and I haven't been on my game for reasons unknown to myself. Has anyway else had this problem? I have no cues as to why I have relatively suddenly had such a change in my sex life when initially together it had been great.

I am definitely interested in methods that would help this situation. Though I am not sure if this is due to a mental mindset change or other reasons. Though I am not very certain as to what would be best for our situation for us to be able to enjoy sex as we had before.
<bot>: I've recently been finishing very quickly in bed, don't know what's changed or what to do to fix my problem.
