Iam really sad, how do i change that?

There are a variety of ways you can make yourself feel better. Indulge in a hobby that you enjoy, or if you used to enjoy it but you haven't done it in awhile (this can possibly* be a sign of depression) try to get yourself to do that thing again.

you can also listen to music, exercise, draw, or paint your feelings.

you can't get pregnant from swallowing semen; the taste varies

explanation:

when you swallow semen it doesn't go into the vagina and fertilize the egg; for taste how ever that can be altered by what the man eats suck as pineapple can make it sweeter
