Courtney Love says being sober has ruined her sex life.The 42-year-old singer, the widow of Nirvana frontman Kurt Cobain, admits she no longer has one-night stands since giving up drink and drugs. She said: "The only thing with sobriety is that promiscuity goes right out the window."It's easier to convince yourself that you are in love when you are high. I don't have a pool of men - it's more a Jacuzzi, or even a bucket."Love - who has a 14-year-daughter, Frances Bean, from her relationship with Cobain - also confessed her love life is so depressing she is considering becoming a lesbian. The singer, famed for her wild behaviour, is quoted as saying: "I don't have a boyfriend. This is the longest time I've gone without one. I love to be in love."I wish I could hang with dykes, but I've got cock written all over my brow. I've had so many obsessive relationships. Complete love crashes."
