is this common or this is something i have to worry about?

The stickiness is probably seman that came out of your penis after your erection was over.. A lot of time I feel the need to urinate after orgasim.. Sounds like everything is normal.. But you can always ask your doctor if you feel it is a constant problem.. Good luck!

Thanks for replying. Please tell me if urination followed by erection is normal, because I really urinate just after erection, no matter whether I have go to toilet before masturbation or not. If possible suggest me home suggesions to improve the situation as I don`t like the idea of consulting my problems with a doctor.
