I'm having one this week, although the guy is a male escort that works with the girl for some mmf meetings, I've ensure her that I am straight. Anyone that has had a mmf do you have any kind of useful tips and advice?
Yep.
1. It's not a competition between you and the other fella, so leave your ego at the door
2. Double and triple check any hard rules (for yourself and the others) if you're nervous. They aren't going to blink an eye if they're both SP's.
3. Make sure you're also up for a laugh. Unless you're heavily into roleplay and want it to be like a porno with a terrible story, you'll have the best time if you don't take it too seriously. MMF threesomes are great fun anyway, so the sex is almost guaranteed to be good.
4. If you're DP'ing the woman, and it's the first time you've done this, you're gonna be in physical contact with the other guy. Maybe even his cock and balls - they might whack you on the leg, or even your own meat-and-two-veg. Obvs if you're doing DV or DA, you're into a whole new level of closeness with another fellas pecker. If you're not shy, I recommend seeing if she can fit both your cocks into her mouth at once - works for me, anyway!
5. The other guy is an SP, so if you're feeling the pressure, or you can't perform, or you just get uncomfortable, speak up and ask him to bugger off for a bit. You're the customer.
Relax, it'll be great I'm sure.
