Robert Pattinson could never have sex with someone he didn't love.

The 24-year-old actor - who is in a relationship with his 'Twilight Saga' co-star Kristen Stewart - claims growing up with older sisters taught him to respect women and gave him a "romantic" soul.

He said: "There is the idea of the saving love, I believe it. I'm not mushy but I have a romantic soul. Having grown up with two older sisters I have a deep respect for women. Sex and feeling for me go hand in hand."

The British hunk admitted he feels uncomfortable when women are willing to expose their bodies and wishes people would dress more modestly.

He told the reporter: "I hate the lack of prudishness, I get bored when people are ostentatious of their body."

The 'Water for Elephants' star also spoke of his desire to settle down and have a family, revealing he dreams of sharing his home with a number of children.

He added: "I'm not interested in casual relationships, I need to know people, I'm not making an existential statement here, simply, I want a family with two or three kids."
