Yes, for many reasons. Firstly, it is widely considered immoral, as marrying your cousin would be incest. Secondly, if you were to have children, scientifically, they would be weaker and sub-par in comparison to other people of their age. This is because the fetus would consume similar hormones from both you and your cousin (for example), which would contradict healthy development and thus be harmful for your child. Also, it would be more "dangerous" if your child were to marry his/her cousin, and if this trend were to follow. This would result in a weaker family line, both physically and mentally.
It isn't not allowed it would just be awkward.In many jurisdictions, marriage between cousins, in some places even between First Cousins, is permitted.
All cousins are related. Those who are related by marriage are not biologically related so developing a relationship with them is only a matter of convention. However, even marriage between first cousins is not unknown and is legal in some jurisdictions.
No, most regions have laws against marriage between people with a blood relationship that close. However, marriage between cousins that are second or further apart is legal.
Yes, in most cases, in most places. Some places restrict marriage between first cousins.
Depending on where you are, there may be no restrictions on marriage of cousins. Others limit it to first cousins only.
No. Fifth cousin marriages take place all the time in communities of moderate and even large size, and in many cases, no one even knows that such a relationship exists between the two people.
No... unless you are fourth cousins. Sorry
