The 24-year-old singer - who has previously raised concerns about casual sex hurting her ability to be creative - admits she likes to keep physical acts of love to those close to her.
She told AMP Radio: "I have weird superstitionsabout sex. If you`re not having sex with someone who really cares about you or who really loves you they can screw up your energy.
"I think sometimes, I don`t know, if you are promiscuous and are just sleeping around that people can take things from you. I think it`s always important to be making love."
The `Alejandro` singer is believed to have got back into a relationship with ex-boyfriend Luc Carl recently, despite him having a girlfriend when she went back to the New York bar she used to work at to meet him
A source said: "Luc was like the cat that got the cream. He had the most famous woman in the world vying for his attention and a hot young blonde waiting in the wings.
"It could have ended really badly, but the other girl melted into the background. She knows what Luc`s like - he has women all over the place... Gaga has convinced herself that this time she`s got Luc back for good."
