Code E7. Double Head Dong For individuals: If you are taking a double penetration dildo by itself, you can use it in several ways. With a single elongated dildo, you can use it for anal or deep vaginal penetration or fold the dildo in the middle and insert both ends into your vagina or backdoor at the same time. You can pull and push the dildo in and out of your holes by controlling it from the centre (the bent area). For couples: Double-ended dildos provide more variety for couples compared to using them alone. For lesbian couples, you can try vagina-vagina, anal-anal or anal-vagina penetration; for straight couples, vagina-anal or anal-anal are options for you; and for gay couples, dual anal penetration is the best way to get all the pleasure you want from a double-ended dildo.
