Love kissing is kissing mouth to mouth. It is one enjoyable way of expressing emotions towards someone you like. You cannot usually get Sexually Transmitted Infections (STIs) from kissing. You get STIs from sexual intercourse or oral sex. Kissing is very low risk for passing HIV, but herpes and other STIs can be transmitted if there is an open sore on infected person or open wounds/cut in an infected person's mouth.
