No, it does not make much sense at all.
The first clause is the worst part. One is only born once, and the "I used to..." construct is for continuous events. "I was born" is correct, but one wouldn't really say that.

A good adjective to use to describe this is 'juvenescent.' 'Jejune' works as well, but has some negative connotations.
It's gobbledygook...what you're trying to do is combine "I used to have" (infinitive) with "I have been born" (present perfect), then apply the "to have" (infinitive) to "I have never grown" (present perfect). It's garbled and nonsensical. From what I can tell, it looks like the meaning the sentence is attempting to convey is, "I was born and since then I have never grown up."
