need to translate into latin

NVLLA potest mulier tantum se dicere amatam
uere, quantum a me Lesbia amata mea est.
nulla fides ullo fuit umquam foedere tanta,
quanta in amore tuo ex parte reperta mea est.

or in english

NO woman is so able to say she was loved
truly, as much as my Lesbia was loved by me
no such faith was there ever in any treaty
as much as was found from my part in my love of you

probably too long for a tatoo but you did ask ...

*in case you wanted to know: written by Catallus a contemporary of
G. Iulius Caesar
