about sperm

I am fond of eating a lot of sperm.
But I have sex with only one guy at a time and his sperm is not enough for me ie. I want more sperm to eat.
To solve this problem we both decided to store the sperm in the cup after sex, then after some time we have sex again and then store the sperm in the cup. We do this many times and when sufficient sperm is stored I eat it all.

Now my question is that can we store the sperm for a long time in a open cup, and is this sperm is safe for me or not

If you're eating the semen of an STD-free male then there are technically no health risks involved. In actuality, semen is loaded with high amounts of protein, and also important minerals like zinc, calcium, and magnesium. From a nutritional standpoint, it has been compared to egg whites. Although sperm won't necessarily spoil like food does, it isn't going to stay desireable for you if you leave it out in an open cup. If you really want to save it for long periods of time, your best bet is putting it in a covered container and putting it in the freezer - although I am not sure exactly how it will be thawed out. If you leave it sitting around in an uncovered cup then eventually it's going to get dried out and crusty. Needless to say, sperm consumption should not be used to replace a normal diet and you should make sure that this doesn't turn into an addiction. Likewise, be weary of STDs because some can be transferred through the consumption of sperm (i.e. gonrrhea or chlamydia).
