Ivo seems pretty pissed about Ruslan. You can think what you want about Ivo but he cares for his wife and protects her. He would never treat her like Ruslan treats his girl
Dont think Alex is so dumb. Alex and Jacky are like good friends I think who are drawn sexually to each other. Thats for sure. But they wont do more because they both have girl / boyfriend
Nope dont remember him. But I think it can be a good thing to help people to have joy and fun having sex again. So nothing bad and nothing to be ashamed of
