Salaam Burhan,
The human, being a sexual creature, is apt to get aroused wether they are conditioned to appreciate nudism or not. Babies, children, young adults, and adults alike get aroused. In society women can be a source of arousal even if they are clothed, even if they wear hijab. Same as men. Different aspects of a woman turn a man on, her eyes, the way she looks at you, her lips, her butt, her breats, her hips, legs, the way she moves, etc. Likewise women are turned on by a man with a nice chest, smile, eyes, butt, etc.
In some religions, Christianity and Earth-based followings, clothing is there because it protects against the enviroment, not the shame of one's body which God created perfect or which is completely natural. They will worship before God/the gods naked to come to their superiors open. It is also a rejection of the traditions of the world which teach that the body is a bad thing, that must be covered because it is shameful.
However, we see that whether the body is covered or not people will feel shame or aversion towards it. Babies can be conditioned early on and social interactions (positive or negative events) can lead to a healthy upbringing or a bad upbringing. The child who is told that playing with him or herself is evil and has their hand slapped away from them in the living room with other family a # of times and in different contexts will grow up fearful of touching themselves and when they do see it as evil.
Take care.
Joe
