“ Female competition is when you are with a guy you like and you look around, see that you're the prettiest girl in the vicinity and feel a huge sense of relief that there's no one to take the attention away from you. (Female competition is a result of women feeling like their greatest sense of self worth , identity and influence comes from their sexual appeal to men. Many women don't even realise they are feeling this way and it's a subconscious thing, but they notice themselves getting jealous when they see other women who they think men would find sexually appealing.) ”
