hi,thank for query.There seems to be some digestive problem most
indigestion due to some food you have taken.Take light diet,more of liquids, avoid junk food and take
antacid that you have,mostly this should help.Sex has nothing to do with this.Take more liquids like juices,soups etc.Do not lie down immediately after food.Avoid strenuous work,if not comfortable talk to your doctor.
wishing you good health.
