Ashleigh began talking about the subject when Shievonne Robinson asked the girls of the house whether they would prefer a nice guy with small genitalia or a horrible boyfriend who was amazing in bed and hung like an "elephant trunk".
Becky Hannon replied: "If I fell in love with someone I couldn't turn them down because of the size of their..."
Ashleigh also initially agreed, commenting: "I wouldn't go for someone like that, if someone told me to 'shut up', I would tell them to 'f**k off'. I don't give a flying f**k about the size of your penis."
However, she added the caveat that she also wouldn't stay with a man, even her current boyfriend in the house Luke Scrase, if he was useless in the bedroom.
"Amazing sex is a big part of a relationship. Either you have got it or you ain't. I'm sorry if you ain't. that's it," she said.
"If you don't have amazing sex... you need that passionate connection. If he's f**king me like a f**king rabbit, I'm not going to have that.
"Luke [Scrase] might be everything I want and he is, but if he isn't passionate in having sex, then I just couldn't."
