No they don't..too much baggage.
In Dragon Ball Z, there is no romantic relationship between Trunks and Pan. Trunks does not fall in love with Pan in the show. Trunks does not have a significant romantic relationship depicted throughout the series.
...If I Ever Fall in Love was created on 1992-12-22.
If You Ever Fall in Love Again was created in 194#.
No, it's never revealed who Trunks marries or if he ever falls in love. Same goes for Pan, Bra, Uub, and Marron. It's never even revealed if Goten marries Valese(his girlfriend in GT). He does show lot of concern for Pan in GT, teases her a bit, and even re-assures her when Goku leaves for good, but it seems that it's just a brotherly/sisterly friendship as far as the series lets on.
It is possible.
no she was a virgin
