Seed cycling is a dietary practice that involves eating certain kinds of seeds – flaxseed, pumpkin, sunflower, and sesame seeds – during the menstrual cycle or at certain times of the month.⁠
⁠
The rationale behind the method is that the seeds will help the body have a healthy balance between estrogen and progesterone. In turn, this is meant to help regulate the menstrual cycle and improve fertility, and it’s also been claimed to reduce symptoms of PMS, PCOS, endometriosis, and menopause.⁠
⁠
Seed cycling itself is not new, but it has gotten more attention and become more widespread in recent years through social media and the wellness industry ✨⁠

Until recently, squirting and female ejaculation were considered to be the same thing. However, research shows that these are actually different 👀 While squirting can often produce enough liquid to wet the sheets and is similar to urine in its composition, female ejaculation produces a smaller amount of milky fluid. This fluid is produced in the Skene’s gland (sometimes called the female prostate) and exits through the urethra with sexual release 🫠 It is possible to experience both squirting and female ejaculation at the same time, while some people will experience one but not the other. ⁠
⁠
While the fluid produced when someone squirts is similar to urine, it’s not the same as peeing during sex. Squirting is different from sexual incontinence (also called coital incontinence) when the bladder leaks during intercourse — this usually happens if you already have urinary incontinence, e.g., you let out a small amount of pee when you laugh or sneeze.

Condoms are a non-hormonal, barrier birth control option ✨ The external or male condom is the most commonly used. There’s also another kind called the internal condom.⁠
⁠
You can buy condoms as an over-the-counter birth control method in supermarkets, drug stores, and pharmacies 🏪 As well as a means of preventing pregnancy, condoms are also useful for preventing the spread of sexually transmitted infections (STIs) 👍 Follow the link in our bio to learn more about condom effectiveness and more! 🔗
