Hi Natasha, I really wouldnt take anything like pt141, you dont give any clues about yourself, are you in a happy relationship, are you on the pill, this could be affecting your sex drive, and a change might be a good idea are you peri menopausal? Is this a new problem or has it always been like this? Are you lacking sleep or suffering from depression? I think you should try to tackle the underlying cause before resulting to drugs, is your partner taking the time that you require to get you in the mood?
anyhow good luck I hope you sort it !
