Are a wife's bold actions, such as asking for a hug and a kiss immediately after the marriage contract, normal and acceptable, and what is the appropriate advice in this regard?

What you mentioned about your wife does not warrant worry or suspicion. The fundamental principle is to think well of Muslims and interpret their words and actions in the best possible light, as Allah Almighty says: "O you who have believed, avoid much [negative] assumption. Indeed, some assumption is sin," and as the Prophet, peace and blessings be upon him, said: "Beware of suspicion, for suspicion is the falsest of speech." There is no blame on one who engages in what Allah has made lawful for him. We advise you to complete the marriage whenever you are able.
