im 17 this yr and i love to mast too, do tt often with my
bf...though we haven't actually had actual sex yet, im afraid will
be very pain..
anyway i heard tt the blood is due to your first time your
vagina has this layer of skin which broke and tt is why it will
bleed a lill..
and about your mast prob, you can try to sleep only when you are
really tired so tt you wont mast, and try to keep yourself busy
with sch or cca so tt you wont have time to think of sex or
what...
