Translation:My boyfriend has never drunk beer.
Yes, it's not standard English. You've used the simple past form as the past participle.
Either "My boyfriend has never drunk beer" 0r "My boyfriend never drank beer"
Consistency would be helpful. Drank is used in a similar example referring to a girlfriend. I agree drank shoul be accepted in the past tense as it is now accepted usage. Incidenally all a dictionary is in English is a record of acceppted usage which may change over time
