Lol hell....... foreplay is basically dating someone up until the point you FINALLY become intimate! All the late phone calls, going out on dates and mentally obsessing about if the person is good in bed or not, kissing each other affter those dates where you dont know if "this is the moment or not", etc. Basically teasing yourself until you have a sense if that person might be someone that you could invest your time in.
For me its growing to know and love my man..he eyes,his masculine smell with a hit of subtile aftershave..his hands seemed specially made just to stroke my cheek,his breath fanning my neck as he whispers my name..feeling the heat of his body as we sit close to each other...so many little things through the day. Its not just about sex...its just us being part of each others body and soul, our very being in the eternal dance of LOVE.
I have never heard a good definition of "foreplay." For me it wouild be the smile, the seductive glance... that particular touch... and possibly a kiss on the neck... after that... I would consider some fondling of private parts... keep kissing... unbuttoning buttons or undoind zippers... that is getting into sex.. and loving your partner with your mouth... or your private parts... that is all a part of sex as far as I am concerned... and yes.... for me... oral sex is as much sex as penetration... and maybe better !!!!
