A run of the the mill strap on is usually more about pleasure for the person receiving, but there’s an erotic element for the person wearing it. The simulation of the act is really exciting – consider it a great form of foreplay for you. You’re pleasing your partner and it’s also a bit of a trip. 😉 Think about what it’s going to be like looking down and watching as you thrust in and out of your girlfriend…the way she’ll be moaning…the look on her face…
It’s very much a visual/psychological pleasure you’ll get from using it on someone.
However! It doesn’t mean that you won’t experience any physical pleasure from wearing the strap-on as well! Depending on how aroused you are and the position you keep the dildo, you can orgasm from that alone. The friction from the base of the dildo or the strap can be stimulating enough for an orgasm. Everyone is different, so it may or may not be enough for you, but you will experience some kind of physical pleasure no matter what. Trust me!
You can also get a dual pleasure strap on, one that has an insert against your clit (it’s like the rabbit part on the rabbit vibrators) or a dildo inside of you as well.
There’s also the Feeldoe which is a strapless double dildo. Using it without a harness requires you to have really strong muscles down there to be able to hold it in place. 90% of women just can’t do it, it keeps slipping out, so I really just advise you to get a harness no matter what toy you get. It takes a lot of pressure off you and it means less work, which means more pleasure. 😀
There’s tons of different versions of a double dildo, the feeldoe is just where it started so you can find them anywhere.
Also, just a tip, if you’re going to wear the harness, let your girlfriend pick the dildo. What works for you, might not work for her, and she’s the one receiving! So that’s something you two need to do together or have her do it.
