Britney Spears admits she isn’t the same sex slave as she was during the “I’m a Slave for U” days … but she says she still LOVES to get down. Spears confessed her love of coitus during an interview for her documentary, “I Am Britney Jean” …. saying, “I love sex. I think sex is great … but I feel a little different about it now that I’m older. Sometimes I feel like I’m 20 and then sometimes I feel like I’m 50.” Funny cause she just mentioned that she’s been wanting to tone down her sexuality. She recently said she was being pushed too far sexually in her music videos and in the “Britney Jean” doc, she implied her most sexually charged concert performances are behind her. Hm!
