penis's are shaped they way they are, with the head and the hood thing at the base of the head, is so that it can scrape out the ejaculate of the previous male that has been in there as you thrust in and out
1. After fucking it's nice to take a shower, so there wouldn't be any cum in her pussy;
2. If there is, hat means there was a person fucking her and now it's my turn? No way.
In real life terms, a girl that just got fucked by another guy is not concentrating on me, and probably not even conscientious. So no, that is not hot.
