Is it illegal to kiss a guy if I'm 16 and he's 23?

In my interpretation of the law below, I would say kissing is not illegal in this situation, but could be risky if it were to lead to something more.

Sec. 11‑9.1. Sexual exploitation of a child.
(a) Any person commits sexual exploitation of a child if in the presence of a child and with intent or knowledge that a child would view his or her acts, that person:
(1) engages in a sexual act; or
(2) exposes his or her sex organs, anus or breast for the purpose of sexual arousal or gratification of such person or the child.

(a‑5) A person commits sexual exploitation of a child who knowingly entices, coerces, or persuades a child to remove the child's clothing for the purpose of sexual arousal or gratification of the person or the child, or both.
(b) Definitions. As used in this Section:
"Sexual act" means masturbation, sexual conduct or sexual penetration as defined in Section 12‑12 of this Code.
"Sex offense" means any violation of Article 11 of this Code or a violation of Section 12‑13, 12‑14, 12‑14.1, 12‑15, 12‑16, or 12‑16.2 of this Code.
"Child" means a person under 17 years of age.
(c) Sentence.
(1) Sexual exploitation of a child is a Class A misdemeanor. A second or subsequent violation of this Section or a substantially similar law of another state is a Class 4 felony.

(2) Sexual exploitation of a child is a Class 4 felony if the person has been previously convicted of a sex offense.
