<human>: Can you provide a brief overview of the text?

Dating a girl for a few weeks. Like[d] everything about her. Tons in common, get along great, took it slow for once. So I actually like her personality. But...we slept together for the first time last night, and I was basically repulsed by her body. She has some scar/stretch marks which I can't really describe. I felt bad during, like I had to maintain arousal to bypass the sudden grossness I felt. I feel like a total asshole, how to go about this the nicest way without it being obvious it's due to my sudden physical unattraction to her after sex? Should I go on another date as we had planned and do it after, so it seems less related to last night?
<bot>: After seeing woman I'm dating naked for the first time I have zero desire to continue dating her, how do I sever ties in the nicest way possible?
