You seem to be confused. Sex and marriage - both are completely different. Don't interlink it. What you are doing is normal, but if it stays for long duration with increased intensity then you may harm your system. In your case it seems to stress induced change. It needs to be addressed with counseling sessions and homeopathic medicine if required.

No, a person cannot be considered mentally ill if he is engaged in masturbation. It is not a psychiatric illness. When it comes to marriage, it is an individual's choice. If he is not mentally ready due to any reason he should not get married. Sex and marriage are two different things. Physical needs can be fulfilled without marriage. But at the same time, engaging with multiple sex partners is not good and one should always promote safe sex. 

Hi, consult a psychologist if you think that your habit is coming in the way of your normal life.

Hi..plz connect  psychologist  to  resolve  inner conflicts.

Hello! Kindly discuss your concerns with a psychologist in person in details so that your questions are addressed correctly and relevantly.

It is not at all a problem it is natural. Need to take more and more responsibilities and work on those.

Yours is a straightforward question – is masturbation by a person deprived of a sexual partner (from the opposite sex, mostly) a sign of mental illness? The answer, in my view, is ‘no’. Sexual needs of all living beings (the way they existed in them) are nature-given. As humans developed over hundreds of centuries and started living in more and more evolved social environments, many societies formed social and moral restrictions on people’s sexual behaviours. That brought in the ‘dos’ and ‘don’ts’, rules, laws etc. which might have been the needs of the times the concerned societies existed. The result is that many of such living environments conditioned their people to treat sex as a topic of taboo. Yet, for any person sexual feelings remain to be nature-given and satisfying those feelings and needs in a legally, socially, ethically, morally and physiologically acceptable way, without harming the freedom of choice and personal rights of any other person involved, in my view, is, and will continue to be, natural. This answers the second part of your question too.

Hi... The two things you have mentioned are interrelated but not directly related. Sex is an important ingredient in a marriage and feeling attracted to your partner is important. But it cannot be the basis of a marriage. Primary purpose of marriage is to raise a family of your own before your parental family completely disintegrates naturally by old age and grown up offsprings going out to pursue their careers or creating their own families. Marriage is an institution to help people have a family of their own. Sex is only one piece of the puzzle. About masturbation, it is a completely natural and does needs to be treated in any way. Yes, if it is creating issues in a person's daily life functioning than it needs to be regulated. About not being able to be emotionally ready to get married. It certainly requires professional help if you wish to get married but such fears are inhibiting you from doing what you want. Economics of marriage can be worked out if both partners are working and ready to share various roles and responsibilities together.
