Right of way, as in “You've got the right of way”, may work. From en.wiktionary, right of way has a sense “The right to proceed first in traffic”. Such a sentence may be used figuratively to tell someone to go ahead.
Also consider the phrase clear sailing. From idioms.thefreedictionary.com, clear sailing means “a situation where progress is made without any difficulty”. Your example sentence might be recast as “Don't worry, I'm a lesbian. You'll have clear sailing”.
