Don't have random threesomes with people in your life circle. Many people will think that having a three-way hookup with their friends, co-workers or neighbors is a good option, but that's not the case, especially when random dates happen. Because a hasty unprepared threesome can only lead to one consequence, that is the three of you don't get along. So, in the event that you learn of such an outcome, it is better that you make some necessary preparations instead of regretting it afterwards.
Don't let anyone feel alone in a 3some. A perfect threesome date is capable of satisfying all the participants, but it certainly doesn't count as a perfect experience if any of them aren't involved. If you don't think you're guaranteed to be able to apply the experience evenly to your two partners just yet, don't take it lightly, because you'll let your partner down.
Do make sure you have set boundaries in advance and you will follow them strictly. Don't think that doing so is a waste of everyone's time; instead, these boundaries mean a lot about whether your date goes well and is successful. What's more, once the boundaries are set, stick to them strictly, because it's about your personal credibility. The biggest difference between a threesome and another relationship involving just two people is here, because the three of you will have your own different expectations of it.
Take the necessary security measures. Whether it's for yourself or your partner, taking the necessary safety precautions is a must. Although you both assure each other that you are free of any transmittable STDs or otherwise, this is no reason to ignore your protective measures. You must be aware of the seriousness of the possible consequences of doing so, and you who are wise would certainly not be willing to take such a great risk.
