Could you please explain why the gender changes after each sexual encounter?

[cola2020]

Hello, my English proficiency is not very good, so I used a translation software. Please bear with me.

 

I want to play with a futa character, so I set the gender of SL to male. However, every time after sexual activity, the gender setting of SL changes to female. Does anyone know why this happens?

 

Please help me.thanks。

it is like bee stinger, penis detaches and is left behind in victim.

It happens probably because you're trying to play Sexlab on Fallout New vegas.

Any ideas on how to recreate this bug?
