use a penis sleeve /extension ,If you are to small for for a extension , Try a 69 & big dildo
And for those ous who aren't ready to admit that MY penis will NEVER be good enough to ACTUALLY please a woman?
Me and my wife are both fairly heavy. By today’s standards definitely considered obese. I do have a small penis. I will try to describe a position we discovered when we first got together 4 years ago. She lays on her back I am on my left side with her right leg over my hip my left leg is under her left leg. I am easily able to enter her easily. We have since found pillows are our friends with other positions. I will also say when we first started it was challenging to find a position that would work. Patience and practice is key. We got good with other options ( oral and our hand). Another piece of advice. We finally started trying different positions before things got hot and heavy basically before forplay. Actually became a form of forplay. We are in our 50s and both previously married. We are both having the best sex of our life’s.
