Sexual fears can stem from many sources, the majority of them being psychological:
Low self esteem When someone is suffering from low self esteem, they can frequently lose the vigour for life and sex is definitely not high on the agenda. If the self esteem problem is not tackled then the lack of interest for sex can spiral into a fear of the act. A possible solution is for the couple to be open and help each other through.
Relationship problems When a relationship goes through a bad patch it can greatly affect the sexual activity of a couple. Sexual tension can be caused by anger and insecurties which lead onto reduced sexual desires and even no sex at all. In these cases getting councelling can help re-establish the relationship and maybe iron out issues playing on the couples mind.
Person issues Someone maybe put off by their partner due to physical or personal problems. Over time the partner may have put on subtantial weight and dont seem as attractive; or they may have hyegiene issues which are a turn-off . Being honest and up front to the partner is the only way to resolve this problem.
Bad experiences Perhaps the most common root of sexual fears stems from previous bad experiences. Maybe they were subject to some negative comments from past partners or have been traumatised by previous events. Seeking advice from a trained counseller can help overcome these fears.
Spead of infections With more and more people testing positive for sexually tranmitted diseases, media coverage and social awareness have never been higher. Some people can develop a fear of sex because of the fear of catching a disease. Educated and common sense is the key to unlocking this problem. Reading up on various diseases and contraception dispells many myths.
