<s>[INST] Im in a relation with an older woman... We hav decided to move on and hav a life together... Im infact happy wit the size of my penis and neither she has complained abt the same.. While in missionary position i cum soon... But when she is on top of me im able to control... My concern is if i use viagra called muslipower will i be able to help her reach orgasm without me ejaculating soon... Im awaiting your response Sanjay [/INST] Thanks for asking in healthcaremagic forum  Do not take self medication. Kegel exercise can help you a lot. It is the exercise for perineal muscle. Please provide details regarding your age and associated illnesses if any like diabetes/hypertension/neurological illness for further suggestion. All the best. </s>
