Was about to lose virginity and...

We were going through foreplay where suddenly fingering became uncomfortable and I closed up, yep, I became unaroused pretty quick.

To explain further, earlier that day i was fine, we were super aroused about to go for it and the condom didn’t fit... so later in the day we bought larger ones and were set for the night. Now fast forward where we are attempting for the now second time, I wasn’t really in the mood like I was during the day, I don’t know what it’s from... nerves? The fact that I was already in the mood earlier in the day? Too planned?

What do you guys think anu similar experiences?
