Hear me out: when you climax, your brain releases the pleasure hormone oxytocin, which promotes feelings of love and well-being. You also release endorphins, which make you happy, and you enter into a state of relaxation, making it easier to sleep. Now, you don't need your ex to orgasm. You can just DM Trojan — yes, that Trojan — an aubergine emoji and they'll send you some self-love in the form of a free vibrator and lube to "sexplore" at home with confidence.
