London: Pop star Katy Perry says she is not strict about relationships but won't indulge in one night stands.

The 29-year-old 'Roar' singer split from Russell Brand in 2011 after 14 months of marriage and called time on her on/off relationship with John Mayer in February, reported Daily Mirror.

Perry says she doesn't have rules when it comes to getting intimate with a man, but she believes there should be a connection. "I'm not like Professor Higgins with my sex life.

I'm not super strict. For me, the most important thing about sex is connection," Perry said.
