Ženský orgasmus je komplexní psychosomatický proces. Přestože existuje celá řada definic ženského orgasmu, většina z nich se shoduje, že se skládá ze dvou komponent: z tělesné složky, kdy dochází k uvolnění neuromuskulárního napětí v těle ženy v reakci na tělesné dráždění, a z psychologické složky, kdy ženy pociťují sexuální naplnění a uspokojení....

Project
The ‘Paraphile’ project is the first project aimed at promoting a programme of primary prevention of sexual delinquency in the territory of the Czech Republic. It is guaranteed by the Laboratory of Evolutionary Sexology and Psychopathology of the National Institute of Mental Health (Klecany, Czech Republic) and had received a subsidy from the operational programme of the Ministry of Labour and Social Affairs (ESIF OPZ). The goal of the ‘Paraphile’ project is to develop and implement in practice a programme of primary intervention and to evaluate its effectiveness. The project should take 42 months and it was launched on 1 September 2019. It is inspired by programmes of primary intervention for paraphiles that already exist in several European countries (e.g. Dunkefeldt, StopItNow, StopSO). The target group should be non-delinquent (in terms of hands-on crimes) self-identified paraphiles whose sexual preference includes unusual objects (e.g. paedophiles, who focus on prepubescent persons, or hebephiles, who focus on pubescents), or unusual activities (for instance those who engage in sexual sadism, pathological sexual aggression, or exhibitionism, i.e. activities which include some form of non-consensus on the part of the sexual object or violence during sex). In response to the widespread phenomenon, we expanded our target group to individuals with risky sexual online behavior. Another problem we would like to address is non-existent care for juveniles with problematic sexual behavior. This intention is beyond the scope of Paraphile project, so another special project focusing on juveniles will be submitted in the near future by our team. The project website has been launched in November 2019 (https://www.projektparafilik.cz/) and online anonymous counselling website has been launched in February 2020 (https://parafilik.cz/).
