Whenever we get some steamy alone time, he always fingers me and it's awesome, but i feel so bad because i haven't returned the favor yet.  to be quite honest, i know very little about dicks, and the only dick i've ever seen was his.  he tried to kinda guide me through a hand job once, but i was so nervous and uncomfortable that i only stroked it gently for a few minutes before stopping.  i was just afraid to look at it and stuff.  i'm very inexperienced and i just need some advice on how to pleasure my guy and get over my discomfort and angst.  Thank you!
