Oral Sex

Using the mouth and tongue to pleasure and stimulate the penis or the outside of the vulva (and the clitoris). There are contraceptives that can be used as a barrier to avoid the transmission of STIs through oral sex. Also known as going down on someone or 'eating/licking someone out'.

Orgasm

Known as the peak of sexual pleasure. The feeling can last for a few seconds, and someone may ejaculate/come. Orgasms are different for everyone and not everyone has an orgasm every time they have sex.

Ovaries

Ovaries are the female reproductive glands. They hold and develop eggs. They also make hormones called oestrogen and progesterone.

Ovulation

For people with a female reproductive system, the ovaries produce eggs. This usually happens in the middle of the menstruation cycle. For instance, if someone has a 28-day cycle from the first day of their period to the next, ovulation will be around day 14.
