25 NL - Flopped straight and draw to flush

[BPMaR]

Table is loose passive
Should I have raised the UTG limper w JTs on the BTN or was the limp behind ok?
Should I have played this slower? They are calling stations.

I'd raise it PF. As you said they are calling stations so you want to keep value betting . I think you played it fine.
