Dear jumiaz,

Yes. There are a number of physical changes that occur when a person is sexually aroused, including enlargement of the breasts. In both girls and guys, the heart begins to beat faster and blood pressure rises. The muscles in the body grow tense, and the nipples may get hard. People with light complexions may have what's called a "sex flush" — they redden around the chest and neck.

In girls, breasts enlarge, the vagina lubricates, and the clitoris begins to swell. The clitoris and the penis are very similar. They're both made of spongy erectile tissue and are full of sensitive nerve endings. The clitoris extends into the body for several inches and the penis extends out from the body for several inches. So, women — much like men — get erections, too. But they're not so noticeable from the outside.

Hope this information helps!

Take care,
