'ach wejHa' loDnal ghajta'mo', manga'chuqlaHbe'..

I don't understand this. Because she has yet had a husband, we cannot have sex.

If you're trying to say because she still has a husband, don't make it perfective. wejHa' loDnal ghajmo' because she still has a husband. If you want to avoid the unattested word wejHa', you can say loDnal ghajtaHmo' because she continuously has a husband.

The English convention of telling stories in the past tense doesn't apply to Klingon.
