I'm in college and of course everyone here is sex crazed but 2 of my friends have mentioned 3 somes or "running train" on girls (1 in the vag n 1 getting head or one fucking and one waiting until there done to get there turn). However, while I'm far from a virgin I have concerns about my sexual intercourse (size being the main concern) I'm not small but having seen their buldges and outlines I feel like I fall "short of the glory" and am hesitant to engage in these activities. Help, advice? lol
