I am recently married and we are planning to have a baby. My penis is very small (abt 2 - 2.5 inch) normal times. It becomes larger to abt 4 inches during orgasm. When I try to penetrate into vagina, my foreskin is very tight and having some uncomfortable feeling, and my size is shrinked down. I applied coconut oil and tried penetration, it went smoothly. But unable to sustain my arousal for long. When I take my penis out, the fluid also comes out which I have ejaculated. My concern is, is this normal thing? Is there any lotion which can be used on foreskin? Can we apply oil in penis? I am not getting full satisfaction during Intercourse. Kindly advise on my concerns. Thank you.
