Is There an Association Between Same-Sex Sexual Experience and Ejaculatory Dysfunction?

Potential effects of sexual orientation on ejaculatory function have been overlooked in the literature. In anticipation of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), attempts have been made to formulate universally suitable definitions for different subtypes of premature ejaculation. However, the proposed definitions are centered around intravaginal ejaculation latency time, and little consideration has been given to whether such definitions are applicable to gay or bisexual men. The present study aimed to investigate effects of sexual orientation on premature and delayed ejaculation. When differences in frequencies and patterns of sexual activities were controlled for, there remained no significant effects of sexual orientation on ejaculatory dysfunction.
