I don't know about you guys, but for me, it's definitely NOT the
same.
I've done it with people I don't love, but now that I've got a
boyfriend, I realise what I've been missing out on. Doing it with
someone you love, there is a sense of intimacy and a very strong
connection, and you feel like both of you are joining together.
Like '2 become 1' kinda thing. It feels less like lust and more
like love.
This is my experience anyway, might be different for others.
