This can vary between couples, some will be ok
to chat afterwards, some may want sometime to themselves to chat about what
happened, how good/bad it was etc. Give them the offer of some space. Don't
crowd them or walk round like a peacock just because you have just had a
shag. This will put them off and you will never hear from them again. If
your good they will take your number and call you whenever they feel like
it. If you swap numbers do not do what 90% of men do in this scenario and
constantly text/phone them. Remember the beginning? They are in charge.
As mentioned before, if they want you, they WILL get in touch.
