"Get into the Know"
The long-term effects of sex without love on a female, can be and is quite often very destructive emotionally, psychologically, and sexually without a doubt.Part of the psychological effect is paralleling oneself sexually to a prostitute, has no emotional connection but at least gets paid for it. So this effect is compounding, because it berates the female and isolates her psychological responses for anyone else that she encounters, without a lot of understanding from the other party. The long-term effects for the male are such that he can lose respect for the female in a general sense of the word because without love, she would probably just lay there without any response, or cooperation on her part.The non participation and response of the female on the male would eventually lead to a mental condition similar to and precipitating a a physical condition known as ED.So under the circumstances it would certainly be counter-productive to continue a relationship of any meaning at the maximum beyond the year.Because after this time I do believe the psychological reparation would take a considerably longer time to reverse.
While sex without love might be good short-term or occasionally for some people, It will not be satisfactory in the long term. The couples will become bored or feel that something is missing.
The reason is simple: Sex is a very intimate thing, and if it is just platonic, the couple will miss out on something. In general, women are more affected since they become more emotionally involved. However in some cases the roles are reversed.
If you are in a relationship and you do not love your partner any more, but you still consent to sex,
then it will lead to resentment.
Sex with a loving partner is better in the long term - it provides a better over-all experience.
