boyfriend cheated

so guys i’m going through a dilemma .. I recently

found out my boyfriend cheated .. but with a transsexual. we are both bi curious and he is very open with me sleeping with women ... but we have never talked about him sleeping with a trans (we’ve only talked of doing it together) .. anywho.. I love him dearly and I don’t want the relationship to die dispite his dishonesty. how can I move on?
