Relationships have been left in ruin because of too few or too many "rounds" in the bedroom. Having a high sex drive or being with someone with a high libido can be concerning in a relationship. That is, if one partner can't keep up with demands.
When in a relationship, naturally, you want to satisfy your partner. No one wants to have needs in a relationship that can't be fulfilled, particularly sexual ones. Much like a person who yearns for emotional intimacy in a relationship, when a person with a high sex drive feels they are not satisfied in bed, their eyes may start to wander.
