To the best of my knowledge, most girls will tend to have a
higher sex urges before and during her period. Some girls dun like
the idea of love making during their period as they believe that it
is dirty and not good for the guy.
Certain days of the period will definitely be heavier flow (example
the second and third days, not sure the exact coz different girl
has different pattern). Avoid those days coz it will be really
messy. However, preventive measures can be done like using a towel
or two place under her butt if it's missionary style. Else try
other styles like she is on-top horse-riding style. Avoid doggie at
all cause, least manageable style. Else change location like do it
in the toilet while the two of you bath together.
As for the smell, some girls have stronger smell than others. Some
dun at all. Never insert your fingers during the period cause it is
hyper sensitive and easier to get infection. And guys, dun juz
think of ur sexual needs, think of the girls too.....wash ur dick
first coz it is sensitive period, and easier to get
infections.
So far, based on my own experiences, there should not be any pain
at all, unless it is done with the girl being tense. But the girls
will definitely be more sensitive and easier to reach climax. And
most of the time, it is the girls who requested/initiated it cause
they are hornier during that period. And it is the guys who mind
more...but if as a guy, you dun mind, I would say it is an
enjoyable experience to have. The feeling is different, soooo
sensitive to you and to her.
Using condoms will cause the discharges to flow down easier and end
up more messy. And technique is important. Dun straight away pull
it out once you are done, coz the moment u pull out, the bloody
stuffs will juz gush out.
