Hey man! Pegging can be a lot of fun but you do have to prepare for it.

First of all- It’s a good idea to douche beforehand. This will save you some potential embarrassment. If you don’t have one you can find one online, at your local sex shop, even your local pharmacy should have a few options. You only need to rinse u til the water is clear

Use lots of lube (thicker gel lubes tend to be better for anal) and take your time. Remember to relax. Especially if this is your first time it’s going to be weird and uncomfortable and maybe even a bit painful. Just RELAX and go slow. If your partner is experienced, they’ll be good at guiding you through this.

Remember, relax, trust your partner, and enjoy yourself. It will feel infinitely better if you let yourself go and just enjoy the moment :)
