In a study of European men, hypersexuality--a preoccupation with sexual fantasy or an excessive indulgence in sexual activity--correlated with proneness to sexual boredom and problems with erectile function.

The study, which included 911 Croatian and 210 German men who were currently in a relationship, contributes to existing knowledge on hypersexuality.

The findings indicate that therapies for hypersexual men should include sex therapy principals that may enhance erectile functioning and address sexual boredom.

"In some men, hypersexual behavior may serve as a coping mechanism for sexual boredom.

In addition, erectile dysfunction within an intimate relationship can accompany this simultaneously," said Verena Klein, lead author of The Journal of Sexual Medicine study.
