"Am a dude of 20yrz.. Damn am kinda a y0uth that's cool.. Am a Ladokite.. Actually I need your advice on how to stop having sex with my gf whenever we are together.. I believe in love and am very romantic,i had my first love when I was in JSS1 at age 9+.. After that I dated like 5 pretty girls before I met my present gf.. To summarize my love story and past relati0nships I love my s0 much gf and she feels the same way also.. We can't do without making love whenever we are alone have tried so hard to like stop it but damn she's so adamant.. We were in school like 2weeks ago i had to go to school to secure and move in to my new hostel so she also came to school to see me cos she missed me.. I was at her hostel for like a week and half, and throughout my stay with her there was no day we did not make love.. I tried everything possible to avoid this but she's so adamant and aggressive..
I don't need you to criticize/castigate me i just need you to advice me.. Thanks"
