Lee spoke with fellow CBB contestants Luisa Zissman, Ollie Locke and Jasmine Waltz about having same-sex partners.
Ollie Locke famously came out as bisexual on his hit reality show Made in Chelsea whereas Luisa has admitted to having relationships with both men and women.
Luisa also hit the headlines for visiting sex clubs and reportedly having a sex addiction.
It had been previously been reported that Lee had engaged in a threesome with his Blue band mate, openly bisexual Duncan James.
When asked about his same-sex liason, Lee said: ‘Yeah I’ve been with a man. Everyone’s done experimentational s***. I’ll tell you later.’
He continued with the frank discussion: ‘Of course, man. I’m a well-travelled person. I’ve never admitted it anywhere. No-one’s bothered to ask.’
Jasmine revealed that she had also been in relationships with the same sex.
She revealed: ‘I went to jail and the only people I had around me was women. I want to feel loved, if that’s with a man or a woman it doesn't matter.’
‘I had a full relationship with this young girl who was 17-years-old from Puerto Rico. She brought me out.’
The group's heart-to-heart took a more shocking turn when Luisa admitted to engaging in group sex, revealing ‘I love an orgy.’
The discussion then came to a steamy conclusion when Jasmine suggested: ‘When we get out let’s all hang out and take our pants off.’
Lee and Jasmine must have felt closer after their candid talk as they later shared a passionate good night kiss.
Things might get even steamier in the CBB house at this rate!
