No string sex is one of the best things that can happen to you. You get to have sex with local women without all of the burdens of a real relationship, like remembering birthdays or anniversaries. All you have to do is remember where to meet and fuck. Here are some tips on making no string sex even more fun:
1. Always remind yourself that this is no strings sex. Remember to remind your partner as well. Both of you are just looking for some sex, and not some attachment. Remember to be clear with your intentions as well. Also, it may be perfectly fine to be friends with your casual fuck buddy, but remember to draw the line there.
2. Your fuck buddy is not your wife or your girlfriend, and she probably isn't the first person you should run to when you need to talk. When you are in a no string sexual relationship remember to make it all about sex and not all about you. Nobody wants to listen to you about your ex-wife or your problems at home. Like you, she is there for sex, so make sure to keep it that way.
3. No strings attached sex is the best way to live out a fantasy and to try new things in bed. Always remember, however, to be respectful of her wants. Remember to try everything. If you both want a threesome, why not? If she wants you to tie her to the bed, go for it. Make the most of your time to experiment and make the most out of sex, but don't cross the line.
4. Don't get stuck with just one girl, try out a few. The best way to have fun casual sex is to rotate sexual partners frequently. This will keep your levels on confidence high, and will make it easier for you to remain discrete and avoid attachment. Who knows, you might even be able to get all the girls to fuck you at the same time :).
