sentences:  A second reason that EPCs may be avoided by a male is that it can be costly to them; their EPC may be discovered, leading to the dissolution of the long-term relationship with their partner and, in some cases, lead to their partner assaulting or even killing them.Men may also avoid EPCs to minimize the risk of putting themselves at increased opportunity for STD transmission which can be common in EPCs.The partners in the EPC may be promiscuous as well leading to a higher statistical chance and probability of contracting venereal diseases; this would counter the lower incidence of STD transmission among exclusively monogamous sexually active couples.
