Forgetting to Prep
It may seem silly to put time into prepping for sex but just a couple minutes of forethought can make a big difference. Not having what you need for sex can complicate things. For example, if you can't find the lube. Lack of prep can also create more serious problems, like if you're going to have sex with a stranger and you don't have condoms. "STDs and HIV don't discriminate and so long as your naked body parts have touched another person's naked body parts, you may be at risk," says Malone.
The solution: Think ahead and make personal considerations. "Do what feels right to you. If you need pillows under here, or a little extra lube there, that is what you need, regardless of what is 'trendy' or 'sexy,'" says Katz. She also recommends doing some stretching if you're considering fancy new moves. You should also get tested for STDs at least once a year and check in on the status of your partner.
