What is making out?

k first of all you dont just jump into makingout you should ease into it maybe just get close to him and put your arms around him even rest your head on his shoulder. If he is even remotly smart he will probly get the hint so you wont suprise him. Im a guy so this is what I do but it would probly work the other way around aswell I take me free hand that isnt around my girlfreind and take it and place it on the far side of her neck then I gently touch her neck and bring my hand down to her chin. than I turn her head twards me and give her a light kiss and take it from there. if he wants to kiss you he will continue. makingout is basically kissing for a long period of time possibly invoving french kissing and ussually involving kissing eachothers neck. Oh and as far as I know exploring eachothers mouth would most likly be refering to a lot of tounge action probly sticking each others tounge as far into the others mouth as you can. if you fell like it try sucking on each others tounges it feels weird lol. I hope I helped.
