I have problem in my sex life l am unmarried but have a beautiful girl friend. We often engage in sex at weekends. My problem is that l don't like to initiate and do foreplay. I tell my girl to what ever she want to make me ready and she do it very well as soon as they a firm erection l penetrate her l don't enjoy if l have to control ejaculation so follow my instinct and fuck hard but always i ejaculate before her. Now what medicines l take so that l enjoy my sex and get such a orgasms that she should not insist for sex at least for four hours. Thanks.
