Wine glasses are only for the aesthetic purposes and unlike pickable items need to be clicked with the "iteraction" icon on instead of the "backbag" icon. If you already have the condoms you only need to speak to Gina and choose "I'm ready to satisfy you", the option to use them should be available in her couch conversation.
