If i have a go once a day, every day, then i might get a little squirt and the rest is dribble. If I've got a girl giving me a hand/blow job or sex, on the other hand, I get a good 4 or 5 proper big squirts. Just dont worry about it, if it's still the same when a girl is doing it then they'll probably like the fact that it doesn't gag them/go everywhere.
