The placement of "anymore" leads to ambiguity. Does it mean the weirdos don't fuck pumpkins now but did in the past (did they need the sex therapy then or now?) or does it mean that sex therapy is now also for people who do not fuck pumpkins (sounds misguidedly exhibitionistic anyway).
Revison: Sex therapy is no longer just for weirdos who fuck pumpkins.
And that way you get to end with the "clever" fuck-pumpkins image.
