If I have sex with the sponsor. Chances are they will be undesirable to me o not my preferred gender. If it's not someone hideously ugly. It would be tempting.
Depends on the Sponsor. If they are a female, I'd consider it based on how desirable they are to me. Agreement on protected sex will go a long way too. Otherwise, nope !!!!
Probably not. Why compromise morals for pieces of paper that might mean absolutely nothing one day? Actual fucking no way. Even if it was a sexy asf girl with no personality defects, no fucking way.
