From the evolutionary perspective, maintaining a committed relationship is beneficial for reproductive success but involves risks such as losing a partner or infidelity. People typically prefer partners with similar mate value (MV) to avoid rejection. However, when a mate value discrepancy (MVD) arises, the partner with lower MV might employ mate retention strategies to maintain the relationship. This study investigated whether men with lower MV compared to their female partners used cunnilingus more often and whether this effect was mediated by their motivation to satisfy the partner. Additionally, it tested the moderating role of men's perceived vulnerability to disease (PVD), predicting that men less concerned about disease would show a stronger link between MVD and cunnilingus frequency, given the health risks associated with oral sex. Data from 540 men in committed heterosexual relationships confirmed that a higher MVD-where the man's MV was lower than his partner's-led to more frequent cunnilingus, and this relationship was mediated by a greater motivation to sexually satisfy the partner. However, the moderating role of PVD was not confirmed. We explore the evolutionary perspective that men may perform oral sex on their partners as a mate retention strategy. This behavior potentially serves as a benefit-provisioning mechanism, compensating for discrepancies in mate value., Competing Interests: Declarations.

Research indicates that men view their women partner's orgasms as reflections of their masculinity and sexual esteem. The purpose of this study was to examine this phenomenon in more detail by exploring whether men's feelings of masculinity and sexual esteem, as well as their feelings of accomplishment, were influenced by the method by which their woman partner experienced orgasm. Specifically, 193 young adult men (primarily between the ages of 18 and 24) read one of three vignettes (a partner orgasming from intercourse, from manual/oral stimulation, or from vibrator use) and then rated their imagined feelings of masculinity, accomplishment, and sexual esteem. Findings indicated that men who imagined their partner orgasmed from intercourse or manual/oral stimulation had higher feelings of masculinity and accomplishment than those who imagined their partner orgasmed from a vibrator. We found a significant interaction between clitoral knowledge and vignette condition in predicting masculinity, with clitoral knowledge only predicting masculinity for men in the manual/oral stimulation condition. The results of this study have important implications for sex education and the prevention of sexual problems, as well as for the future study of positive sexual functioning in women and men., (© 2021.

Head neck squamous cell carcinomas (HNSCCs) are a significant cause of morbidity and mortality all around the world. Just like tobacco and alcohol, Human papilloma virus (HPV) infection is now recognized to play a role in the pathogenesis of a subset of HNSCCs. Unprotected sexual behaviours with the HPV carrier plays an important role in transmission of this virus. The global incidence of head and neck cancers is declining, but the incidence of HPV related head and neck cancers is rapidly increasing over the last few decades. However, most institutions do not mandate documentation of sexual history or counselling of patients regarding sexual practices like they do for tobacco and alcohol addictions in HNSCC patients. The aim of this review of literature is to analyse if there is a strong evidence to correlate oral sex with HPV related HNSCC and counsel the patient's regarding sexual behaviours., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Saliva plus DNA from a suspect is commonly encountered in sexual assault cases on bodily swabs. However, without background knowledge, the weight of this evidence is unknown. It may indicate the presence of saliva resulting from cunnilingus, or it may represent indirect transfer. In this study, females who refrained from cunnilingus donated 43 items of underwear and 19 vaginal swabs. The samples were subjected to Phadebas(®) , RSID(™) -Saliva and mRNA profiling and were subsequently DNA-profiled to determine the prevalence of background saliva in the female population. The results report that 15.8% of females who refrained from cunnilingus were positive for saliva and a further 10.5% also had DNA from unknown source(s). These findings of the rate of indirect transfer were evaluated with the Bayesian approach, and it was found that the evidence of saliva plus a high foreign DNA source adds moderately strong support to the allegation of cunnilingus., (© 2015 American Academy of Forensic Sciences.)

Rape of women by men has occurred throughout recorded history and across cultures and religions. It is a crime against basic human right and a most common crime against women in India. In this article, rape is discussed from legal and mental health perspective. In India 'rape laws' began with enactment of Indian Penal Code in 1860. There have been subsequent amendments and the main issue of focus remained the definition of 'rape and inclusion of 'marital rape' in the ambit of rape. Law Commission Reports related to rape and the psychological impacts of rape have been discussed.
