Let your partner know what works for you and what doesn’t. An open attitude towards sex should also relax you more and lessen the nerves that cause a swift ejaculation.
Man is a sexual being and by this I mean both sexes so when you are married you need to let go and enjoy your sexuality to the full ( God doesn’t mind).
As a woman Sex is good for you as well though we don’t advocate that your throw away all care and go looking for the next romp
men are sexual beings and some can’t do without it for a week
Sex was created by God.
