Hello, Thanks for sharing your health concern with us. I have gone through the query and would like to offer some suggestions. Burning sensation during an intercourse can happen due to rough intercourse, lack of lubrication, infection etc. Unless your body produces anti-sperm antibodies, you can conceive with his sperm. However, there are several other factors like absence of infections, proper timing of the intercourse to ovulation and patent tubes which influence conception. K-Y jelly can be used to enhance lubrication if other causes are ruled out. Hope this helps.
