So, if you never want to try it or if you’ve tried it once and didn’t enjoy it, then the obvious but important anal sex tip I have for you is that you shouldn’t feel that you have to keep doing it with your man. If your sex life consists of you doing things that you don’t want to do, then it’s not going to be a particularly satisfying one. Like I mentioned previously, there are plenty more things you can do with your man.
Because most research on anal intercourse addresses men who have sex with men, little data exists on the prevalence of anal intercourse among heterosexual couples. In Kimberly R. McBride's 2010 clinical review on heterosexual anal intercourse and other forms of anal sexual activity, it is suggested that changing norms may affect the frequency of heterosexual anal sex. McBride and her colleagues investigated the prevalence of non-intercourse anal sex behaviors among a sample of men (n=1,299) and women (n=1,919) compared to anal intercourse experience and found that 51% of men and 43% of women had participated in at least one act of oral–anal sex, manual–anal sex, or anal sex toy use. The report states the majority of men (n=631) and women (n=856) who reported heterosexual anal intercourse in the past 12 months were in exclusive, monogamous relationships: 69% and 73%, respectively. The review added that because "relatively little attention [is] given to anal intercourse and other anal sexual behaviors between heterosexual partners", this means that it is "quite rare" to have research "that specifically differentiates the anus as a sexual organ or addresses anal sexual function or dysfunction as legitimate topics. As a result, we do not know the extent to which anal intercourse differs qualitatively from coitus."

Take things slowly, use plenty of lubrication, and stop if it becomes too painful. Don’t aim to have full penis penetration your first go-round. Try using a finger, and then upgrade to two or three fingers. A toy might be a good option, too, as you grow more comfortable with the sensation. After the first time or two, you and your partner will likely find that the pleasure trumps any initial discomforts.
