Right, because rejecting a girl so she feels unattractive and ugly is so much better for her mental health and self esteem!

This type of sitch is a lose-lose proposition, as you can see. There are certain situations where either of two possible responses will open up their own individual can of worms. The best one can do when such a proposition presents itself is to conduct a quick mental cost-benefit analysis (where's Ethan when you need him?) on the fly and decide which of the two may be the lesser evil in terms of likely consequences, at least at the time. Of course, even if it may be the better decision for the moment and immediate future, it could still come back to bite you in the ass later, because that moment will eventually be replaced with other moments of a different climate.

This is what I think may have happened in regards to Baio. He made a decision that wasn't the worst of the two possible choices at the time. He and Nicole gave each other pleasure, she was supposedly happy to lose her virginity, happier still to lose it to a guy she was very attracted to for a long time, and all was well. However, Baio could not have anticipated what the political climate would be like 20 years later, with unexpected fallout waiting in the wings.

For the record, one of Eggert's conflicting claims was that she felt mortified, rather than good, just after having sex with Baio. She claims other people she told about it at the time can back this up. I cannot say for certain what she was feeling or saying after it just happened, other than again pointing out that this contradicts what she said on the interview for that show Baio played a track of audio from on his Facebook message.

There are two possibilities that I can think of:

1. She excitedly told some people about it after it happened, they told her that they thought Baio was an asshole, they quickly made her feel bad for choosing him as her first, and they quickly succeeded in tainting her image of Baio as a person and her happiness over him being her first. In other words, they manipulated her, not Baio.

2. She may have expected a relationship to arise out of the sitch, or at least a continuing sexual relationship, and Baio wasn't down with either for whatever reason. That disappointed her, and she felt rejected in a way and told some people that. This simmered and boiled on the fringes of her psyche for two decades until the "SJW" bandwagon emerged on the political scene, and she became convinced that he "abused" and "manipulated" her, or at the very least she was in a good political position to vent her long-simmering anger at him by claiming such.
