Just as sildenafil has helped treat erectile dysfunction, so may future drugs enhance or inhibit sexual drive, romantic love, and bonding. Enduring attachment between spouses may be associated with high levels of vasopressin and oxytocin, and low levels of testosterone. Little imagination is required to conjure various circumstances when greater happiness would be achieved by changing sexual drive, romantic potential or bonding capacity. Lowering of testosterone levels may become acceptable to maintain a happy long term relationship, while increasing testosterone levels may assist single or divorced men with lower than average testosterone levels to find and satisfy new partners. The same may apply to women, particularly those who have ovarian failure and low testosterone levels.
Sex is now for fun, love and intimacy, thanks to the greatly reduced risk of unwanted pregnancy.
14 Foreplay has increased from 10 to 15-17 minutes in the United States. The sexual act may become more varied as sexual aids, devices, lotions and drugs are developed, with increased knowledge of sexual biochemistry and pharmacology. As standards of health rise, contraception and therapeutic abortion become more widely available, and people become more interested in sex. As women gain economic independence, they become less likely to exchange sexual freedom for protection and financial support. Women are experimenting with sex earlier in life, living with partners outside marriage, expecting a wider variety of sexual techniques, using contraception and planning families, marrying later, and divorcing when spouses do not satisfy their social and sexual needs.
