There are many ways- however, if he keeps insisting on intercourse and you feel he is pressuring you, then you should
not stay with him as he will not care about you in the way you hope for and deserve. No one who pressures someone into something they are uncomfortable with really respets or loves that person, as if they did they would be happy to wait.
If that is not the case, and you just want to think of ways to make him happy then: make him something personal (draw a picture, write a poem etc) and give it to him; buy him little things you see that he will love (just his favourite candy bar or a funky guitar pick [if he pays guitar] or something small relating to his interests; bake him a cake or cook him a meal and sit and eat together; plan a fun day out; rent his favourite movies and watch them with him, or play his games console with him all night. Find out more about him and what he likes, and get involved in his interests. Sexually, to please him, you could touch him, or use your mouth on him, but again, that is if you want to and if that is what you meant by the question.
Being with you should be enough to please him, so just be yourself and try and be upbeat and happy and completely open about yourself with him. He should feel lucky just to have you :) it is the little things that count in relationships, so just make him his favourite drink and do your favourite things together and you should both be happy.
It depends on what you mean by the word 'please' do you wish to please him sexually without intercourse?
or do you wish to please him in a general nonsexual sense?
witty banter on a daily basis, rent a guy flick- boobs guns blood and explosions, food, back rubs, breakfast in bed.
pleasing in a sexual sense without intercourse would include manual or oral stimulation. (but with me that would only lead to intercourse- so that wouldn't work with every guy)
You could just feed him, be around him, give him things. But I really don't see how that's love if he is wanting intercourse with you and not accepting that you aren't ready, but I guess that's just my pov.
make him comfortable around you, some hugs, big smiles, tell some jokes, play some games etc...
If he loves you he shouldn't require intercourse to be happy with you.
Cook him a nice meal everyday?
