Hello.
First, congratulations on your marriage. Secondly, there are many positions for penis-vagina sex, and I recommend you try different ones in order to find those most comfortable and pleasurable for you. Many women find that being on top, for instance, gives them the ability to control stimulation in ways that is very pleasurable. Another position which many women enjoy is side by side. So your husband doesn't have to be on top of you for sex to be mutually pleasurable and fun. Best of luck to you. Dr. J
dont worry. your husband weight will not do any harm to you. you will have take his penis into your vagina thats all. your husband will know how to perform sex.
