I am 23 y/o girl, i have a boyfriend that is 20 y/o. He goes to the gym every day.
We live together in my appartement. Sometimes i travel for two or three weeks as i work for an airline company.
He does not masturbate when he is alone. He does not enjoy doing this to himself. His penis became so sensitive and his balls became so hard and sometimes he feels pain when he does not ejaculate when i am away.
I decided to give him a hand in masturbation. I found that his penis is too sensitive to my hands. Once i touch his penis, it starts oozing some pre-cum drops, and it continues that dripping while i am masturbating him.
It seems that he saves a lot of load inside him for long times without letting it out. For this reason, i cannot move my hand away from his penis until making him cum. This is something very erotic to me and enjoy doing this.
When i come back home, I love to tease his penis and deny the orgasm for a while and enjoy watching him dripping too much before the final ejaculation.
I want to know if this has a bad effect on him or not ?
